AB  - Powder mixture consisted of ZnO, Mn2O3 (MnCO3) and Fe2O3 blended powders, was found laminating during compaction. Polyvinyl alcohol (PVA) and a combination of PVA with polyethylene glycol (PEG) added as a plasticizer, were introduced as polymer binders to improve the compaction of oxide mixtures. It has been done by forming a suspension of oxide mixture and varying the polymer solution concentration and composition. By evaporating the solvent, new materials were obtained, which consist of oxide particles bound via polymer. In such a manner obtained hybrid materials were characterized with attenuated total reflection Fourier transformed infrared (ATR-FTIR) spectroscopy, differential thermal analysis (DTA) and transmission electron microscopy (TEM). The oxide polymer material was compacted at 200 MPa and the expansion of this compact during heating was monitored in temperature range up to 550ºC with dilatometer. It was found that PVA forms graft polymer with PEG and specific interaction with oxide particles surface was revealed.

AB  - A simple organic-phase synthesis process was used to produce bare NiFe2O4 and ZnFe2O4 and core-shell ZnFe2O4@NiFe2O4 ferrite nanoparticles. X-ray powder diffractograms for all investigated powders show characteristic peaks of a spinel cubic structure without a secondary phase. Transmission electron microscopy (TEM) indicated the presence of nanoparticles that are smaller than 20 nm. The release of divalent ions (Ni2+ and Zn2+) from synthesized nanoparticles that were dispersed in saline solution, phosphate-buffered saline (PBS) and human serum, as determined by the inductively coupled plasma mass spectrometry (ICP-MS) method, was lower than 2 wt %. These results demonstrate the stability of the investigated nanoparticles in biologically relevant media and exclude the toxicity of Ni2+ and Zn2+ due to metal ion release, thereby opening a broad range of (bio)medical applications.

AB  - Pt(II) and Pd(II) complexes (1 and 2, respectively) with thiomorpholine-4-carbonitrile (TM-CN), an N-substituted thiomorpholine derivative, were synthesized from tetrachlorido precursors in water. Structural analysis has shown that 1 represents the first monomeric metal complex with this ligand type with an axial M–S bond with respect to the TM-CN ring chair conformation, while in 2 a typical equatorial M–S bond position with respect to the ring chair conformation was observed. A detailed DFT investigation revealed that axial conformers are more stable for molecular forms of both metals, while intermolecular interactions in the crystals stabilize the axial conformer for Pt(II) and the equatorial conformer for Pd(II). The magnitude of this stabilization in the case of 2 is large enough to change the most stable axial conformer in the molecular form to the equatorial conformer in the crystal. Further investigation of the strength of individual intermolecular interactions revealed significant differences of some interactions between the two structures. The likely cause of the difference in the crystal structures of experimentally obtained complexes is the fact that 1 and 2 exhibit different dominant interactions: C–H/M and C–H/S are more dominant in 1 and C–H/Cl interactions are more dominant in 2. In addition, DFT calculations have shown that while the axial position of the Pt–S bond with respect to the ring chair conformation results in a significantly shorter C–H/Pt interaction distance than that in the hypothetical equatorial conformer, there is very little difference in C–H/Pd interaction distances in conformers with axial and equatorial positions of Pd–S bond with respect to the ring chair conformation.

AB  - The BaTiO3 ceramics applications based on electronic properties have very high gradient
scientific and industrial-technological interests. Our scientific research has been based on nano BaTiO3
modified with Yttrium based organometallic salt (MOD-Y). The samples have been consolidated
at a sintering temperature of 1350  C. Within the study, the new frontiers for di erent electronic
properties between the layers of BaTiO3 grains have been introduced. The research target was
grain boundary investigations and the influence on dielectric properties. After scanning electron
microscopy and dielectric measurements, it has been established that modified BaTiO3 samples with
larger grains showed a better compact state that led to a higher dielectric constant value. DC bias
stability was also investigated and showed a connection between the grain size and capacitance
stability. Analyses of functions that could approximate experimental curves were successfully
employed. Practical application of fractal corrections was performed, based on surface ( s) and
pore size ( p) corrections, which resulted in obtainment of the relation between the capacitance and
Curie temperature. Successful introduction of fractal corrections for capacitance-Curie temperature
dependence for a set of experimental data is an important step towards further miniaturization of
intergranular capacitors.

AB  - Iron oxide, in the form of magnetite (MG)–functionalized porous wollastonite (WL), was used as an adsorbent for heavy metal ions (cadmium and nickel) and oxyanions (chromate and phosphate) removal from water. The porous WL was synthesized from calcium carbonate and siloxane by controlled sintering process using low molecular weight submicrosized poly(methyl methacrylate) as a pore-forming agent. The precipitation of MG nanoparticles was carried out directly by a polyol-medium solvothermal method or via branched amino/carboxylic acid cross-linker by solvent/nonsolvent method producing WL/MG and WL-γ-APS/MG adsorbents, respectively. The structure/properties of MG functionalized WL was confirmed by applying FTIR, Raman, XRD, Mössbauer, and SEM analysis. Higher adsorption capacities of 73.126, 66.144, 64.168, and 63.456 mg g−1 for WL-γ-APS/MG in relation to WL/MG of 55.450, 52.019, 48.132, and 47.382 mg g−1 for Cd2+, Ni2+, phosphate, and chromate, respectively, were obtained using nonlinear Langmuir model fitting. Adsorption phenomena were analyzed using monolayer statistical physics model for single adsorption with one energy. Kinetic study showed exceptionally higher pseudo-second-order rate constants for WL-γ-APS/MG, e.g., 1.17–13.4 times, with respect to WL/MG indicating importance of both WL surface modification and controllable precipitation of MG on WL-γ-APS.

AB  - The study of the synthesis of anticorrosive inhibitors, based on chemically modified tannins, and
their use in alkyd based coatings to improve anticorrosive properties is presented in this work.
Two methods of tannin modification were applied: direct method using ammonium hydroxide,
ammonium hydroxide/ammonium chloride buffer or diethylenetriamine (DETA); and a two-step
method including tannin modification with epichlorohydrin (ECH) in first step to produce epoxy
modified tannin, ET, and further modification with heteroaromatic amines or linseed oil fatty acids
(LFA) in second step. The obtained anticorrosive additives were characterized using ATR-FTIR,
1H and 13C NMR spectroscopies and elemental analysis. Epoxy, amino, hydroxyl, acid and iodine
values of the synthesized inhibitors were determined according to standard methods. The
prepared alkyd coating with tannin inhibitors was tested according to standard SRPS EN ISO
4628 method. Anticorrosive coating containing modified tannin based additive showed increased
anticorrosive properties, good adhesion and coverage comparing to the coating with zinc
phosphate additive. The alkyd coating films based on ET-LFA and ET modified with 2-amino-5-
mercapto-1,3,4-thiadiazole showed best anticorrosive results.

Sintetisani antikorozioni aditivi su okarakterisani primenom ATR-FTIR, 1H i 13C NMR spektroskopija, i elementalnom analizom. Sadržaj epoksi, amino, hidroksilnih i karboksilnih grupa i vrednost jodnog broja sintetisanih aditiva određen je prema standardnim metodama.

AB  - The first complexes of 2-pyridylthiocyanate (L) and silver nitrate (1) and perchlorate (2) were prepared
and characterized by a single crystal X-ray analysis. The common structural motif of both 1 and 2 is coordination
of two L molecules via pyridine nitrogen atom to Ag(I). In order to properly describe the nature
of coordinative bonds in 1 and 2, as well as crystal packings in respective structures, a Quantum Theory of
Atoms in Molecule topological analysis was performed. Coordinated nitrate ion provides more electron
density to Ag(I) in comparison to perchlorate ion. Additional electron density in the case of 2 was provided
by the coordination of third L molecule via thiocyanate nitrogen atom resulting in a 1D polymeric
structure. Detailed computational analysis of intermolecular interactions, as well analysis of interactions
between pyridine ring and –SCN group was performed. Antiproliferative activity of monomeric compound
1 was found to be better than of cisplatin on three out of four studied human cancer cell lines.
Docking studies indicate intercalation as a major binding mode of 1 to DNA, while human serum albumin
was revealed as possible carrier for distribution of 1 in the blood stream.

AB  - In this paper, the potential application of phosphorylated industrial kraft lignin (KLP) in improving flame 
retardant properties of unsaturated polyester/KLP composites (UPe/KLP) was studied. KLP mass contents in UPe based 
composites varied from 0.5 wt.% to 5.0 wt.%. The successfulness of the performed phosphorylation method, direct grafting 
of phosphorus chloride on KLP surface hydroxyl groups, and formation of phosphoric acid ester were confirmed via Fourier 
Transform-Infrared Spectroscopy (FT-IR). The effects of KLP surface functionalization and KLP mass contents on the UPe 
tensile properties were studied. Tensile strength (σ), elongation (ε) and Young’s modulus of elasticity (E) of the UPe/KLP 
composites were analyzed in relation to the structure of KLP modification. The obtained composites were tested on fire 
retardant properties according to the standard test method UL-94V.

AB  - Unsaturated fatty acid (FA)-modified nanocellulose (m-NC) shows potential application in improving mechanical properties of unsaturated polyester/m-NC nanocomposites (UPe/m-NC). A polyester matrix is obtained by polycondensation of maleic anhydride and products of poly(ethylene terephthalate) depolymerization with propylene glycol. Two methods of NC modification are performed: direct esterification with oleic acid, linseed, or sunflower oil FAs, and esterification/amidation with maleic acid/ethylene diamine (MA/EDA) bridging group followed by amidation with methyl ester of FAs. Increases of stress at break in the ranges from 148.8% to 181.4% and from 155.8% to193.0% for UPe/m-NC composites loaded with 1 wt% of NC modified directly or via MA/EDA cross-linker, respectively, are obtained. Results of the modeling of tensile modulus, by using the Cox-Krenchel model, show good agreement with experimentally obtained data. The effect of FAs' cross-linking capabilities on the dynamic-mechanical and thermal properties of the UPe/m-NC is studied. Cross-linking density, modulus, and T-g of the nanocomposite show appropriate relation with the unsaturation extent/structure of NC modification.

AB  - During the compaction of the powder mixture of ZnO and Mn2O3 (MnCO3) and Fe2O3 compacts were find fragile for further handling. Poly vinyl alcohol PVA was used as a binder in an unusual 20% PVA content. We made as well 2% PVA with 0.6% Poly ethylene glycol PEG and 20% PVA with 6 % PEG. Binder was wrapped over the powder by suspension forming in the polymer water solution and drying afterwards until all water content evaporates. On the these obtained powders employed characterization techniques were: Fourier transformed Infra red FTIR spectra with ATR attenuated total reflection technique as well as differential thermal analysis DTA on the device with low temperature sensitivity and TEM transmition electron microscopy. All binder concentrations gave compacts with good mechanical properties, that can be handled with ease but with adding, a PEG as plasticizer the operating of the anvil and piston were extremely difficult due to friction.

AB  - The innovative laboratory procedure for the synthesis of copper(II) hydroxide in the form of the aqueous suspension was developed. The reaction mechanism consists of the reaction between copper(II) sulphate pentahydrate and sodium carbonate by successive ion exchange of carbonate ions with the hydroxide ones in a multistep process. Production of copper(II) carbonate and sodium sulphate by reacting of copper(II) sulphate with sodium carbonate was followed by addition of sodium hydroxide solution whereby the product, copper(II) hydroxide, was obtained by releasing an equimolar amount of sodium carbonate. It was determined that, the equimolar reaction of copper(II) sulphate and sodium hydroxide lead to the maximal reactants exploitation. Sodium phosphate, formed in the final process stage by addition of 10 % phosphoric acid solution, acted as a copper(II) hydroxide stabilizer. High yield of the product was obtained by optimizing the synthesis parameters: reaction time, molar ratio of reactants and the reaction temperature. The obtained product was formulated to obtain a commercial product, which is used as a fungicide and bactericide.
AB  - U radu je predstavljena inovativna laboratorijska procedura za sintezu bakar(II)-hidroksida u obliku vodene suspenzije. Procedura se zasniva na reakciji između bakar(II)-sulfata pentahidrata i natrijum-hidroksida. Mehanizam reakcije se sastoji iz sukcesivne jonske izmene karbonatnih jona sa hidroksidnim jonima i odvija se u više stupnjeva. Prvi stupanj predstavlja proizvodnju bakar(II)-karbonata i natrijum-sulfata reakcijom bakar(II)-sulfata sa natrijum-karbonatom, nakon čega sledi dodavanje rastvora natrijum-hidroksida, pri čemu se proizvod, bakar(II)-hidroksid, dobija oslobađanjem ekvimolarne količine natrijum-karbonata. Potom sledi ekvimolarna reakcija bakar(II)-sulfata i natrijum-hidroksida koja dovodi do maksimalnog iskorišćenja reaktanata. Natrijum fosfat, formiran u završnoj fazi procesa dodavanjem 10 % rastvora fosforne kiseline, deluje kao stabilizator bakar(II)-hidroksida. Visok prinos proizvoda dobija se optimizacijom parametara sinteze: vremena reakcije, molarnog odnosa reaktanata i temperature reakcije, a sam proizvod je formulisan radi dobijanja komercijalnog proizvoda koji se koristi kao fungicid i baktericid.

AB  - Production of high-performance nanocomposite materials obtained from unsaturated polyester resin, based on products of the waste poly(ethylene terephthalate) recycling, and modified multi-walled carbon nanotubes is presented. Di-hydroxy functional glycolysates, synthesized by catalytic depolymerization of poly(ethylene terephthalate) with propylene glycol, were used for the unsaturated polyester resin synthesis. The structure of the obtained glycolysis product and unsaturated polyester resin were characterized by using FTIR and NMR spectroscopy, and by acid, iodine, and hydroxyl value. Nanofillers were prepared by direct and two-step amidation of oxidized multi-walled carbon nanotubes. Direct amidation with diallylamine produced multi-walled carbon nanotube-diallylamine reactive nanofiller. Two-step modification with diamines: hexamethylenediamine and p-phenylenediamine gave multi-walled carbon nanotubehexamethylenediamine and multi-walled carbon nanotube-p-phenylenediamine nanofiller, respectively, whose amidation with methyl ester of linseed oil fatty acids gave multi-walled carbon nanotube-hexamethylenediamine/methyl ester of linseed oil fatty acid and multi-walled carbon nanotube-p-phenylenediamine/methyl ester of linseed oil fatty acid nanofiller, respectively. Influences of vinyl functionalities on mechanical properties of nanocomposite were analyzed from tensile strength (sigma(b)), elongation (epsilon(b)) and Young's modulus (E) determination. An increase of 97.4, 119 and 139% of sigma(b) was obtained for nanocomposites with addition of 0.25 wt.% of diallylamine, p-phenylenediamine/methyl ester of linseed oil fatty acid and hexamethylenediamine/methyl ester of linseed oil fatty acid multi-walled carbon nanotubes, respectively. Short techno-economic analysis, performed on the basis of fixed and variable unsaturated polyester resin production costs, showed satisfactory potential profit, which could be realized by the implementation of the presented technology.

AB  - Magnetic macroporous crosslinked copolymer glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGDMA) samples with different magnetite content were prepared by suspension copolymerization and functionalized with diethylene triamine. Samples were characterized by elemental analysis, mercury porosimetry, Fourier transform infrared spectroscopy (FTIR) analysis, scanning electron microscopy with energy-dispersive X-ray spectroscopy, transmission electron microscopy, SQUID magnetometry and X-ray photoelectron spectroscopy (XPS). The selected amino-functionalized sample was tested as a potential sorbent for the Mo(VI) and Re(VII) oxyanions from aqueous solutions. The influence of pH, ionic strength and possible interfering of cations and anions was investigated. Equilibrium data were analyzed with Langmuir, Freundlich and Tempkin adsorption isotherm models. Sorption studies were carried out in a batch competitive experiments, in the pH range 1-8, at 298 K. Obtained results indicate that 92% of Re(VII) and 98% of Mo(VI) were sorbed at pH 2.

AB  - Structural changes caused by mechanical activation of SrTiO3 powders were investigated using a variety of methods. Average crystallite size continuously decreased with increased activation time to around 20 nm after 120 min activation, while mesopore volume and specific surface area increased accordingly. Higher activation times lead to increased agglomeration of nanoparticles to form agglomerates of around 2 mu m in size, ultimately producing a relatively stable powder, which exhibits lower microstrain than powders activated for shorter periods of time. Raman spectroscopy shows that the behavior of TO2 and TO4 modes is consistent with a decrease in particle size, while behavior of the nonpolar TO3 mode is markedly different, indicating relaxation of the inversion symmetry in polycrystalline SrTiO3. UV-VIS spectra show that mechanical activation has negligible effect on SrTiO3, with a slight shift caused by TiO2 contamination due to presence of air. Other than this, the mechanical activation process preserves the chemical purity of the initial powder.

AB  - The structural characteristics of polymer nanocomposites with functionalized multiwall carbon nanotubes (MWCNTs) in poly(methyl methacrylate) matrix have been studied in relation to nanofiller loading and surface functionality. Different functional groups have been covalently attached on the MWCNTs sidewalls in order to induce interfacial interactions at nanofiller/polymer interface, which resulted in an improved nanomechanical features. Structural properties of nanocomposites, studied with XRD and Raman analysis, indicated the most pronounced decrease in a degree of amorphousness for samples containing 0.5 and 1 wt% of MWCNTs functionalized with dapsone (dapson-MWCNT) and diethyl malonate (dem-MWCNT). SEM and TEM micrographs confirmed improved dispersibility of the MWCNTs modified with aromatic structure of dapsone inside PMMA matrix. A significant increase in a glass transition temperature of over 60 degrees C has been found for the 1 wt% dapson-MWCNT nanocomposite. Additional modification of dapson-MWCNT by further increasing aromaticity and voluminosity of attached moiety (fid-MWCNT), showed 30 degrees C increases in a glass transition temperature at 4 wt% of nanofiller loading, which is similar to shift of 37 degrees C with loading of MWCNTs modified with ester terminal group. A maximum increase of 56% of reduced modulus and 86% of hardness was obtained for 1 wt% loading of dapson-MWCNT nanofiller.

AB  - The aim of this work was to prepare and characterize the series of segmented polyurethane nanocomposites (PUNC) modified with poly(dimethylsiloxane) and based on montmorillonite (Mt) as a nano-filler. alpha,omega-Dihydroxy-poly(propylene oxide)-b-poly(dimethylsiloxane)-b-poly(propylene oxide) macrodiol was used as the soft segment component, while 4,4'-diphenylmethane diisocyanate (MDI) and 1,4-butanediol (BD) were selected as the hard segment components. PUNC were synthesized with different ratio of hard/soft segments. PUNC were morphologically, structurally, thermally, mechanically and surface characterized by XRD, TEM, FTIR, AFM, TGA, DMTA, tensile test, XPS, contact angle, surface free energy (SFE) and water absorption measurements. Added Mt (1 wt%) was completely delaminated and well dispersed in the form of mixed exfoliated/intercalated layers in the polymer matrix, and that PUNC have more pronounced microphase separated morphology, higher thermal stability, superior mechanical features, enhanced surface properties, as well as outstanding hydrophobicity. Due to the improved features, developed polymers can be considered as candidates for materials with specific biomedical applications or as waterproof coatings.

AB  - The multistage synthesis of the multi-wall carbon nanotubes (MWCNT) modified with polyamidoamine dendrimers, A1/and A2/MWCNT, capable of cation removal, is presented in this work, as well as novel adsorbents based on these precursor materials and modified with goethite nano-deposit, alpha-FeOOH, A1/ and A2/MWCNT-alpha-FeO(OH) adsorbents used for As(V) removal. In a batch test, the influence of pH, contact time, initial ion concentration and temperature on adsorption efficiency were studied. Adsorption data modelling by the Langmuir isotherm, revealed good adsorption capacities (in mg g(-1)) of 18.8 for As(V) and 60.1 and 44.2 for Pb2+ and Cd2+ on A2/MWCNT, respectively. Also, 27.6 and 29.8 mg g(-1) of As(V) on A1/ and A2/MWCNT-alpha-FeO(OH), respectively, were removed. Thermodynamic parameters showed that the adsorption is spontaneous and endothermic processes. Results of the study of influences of competitive ions: bicarbonate, sulfate, phosphate, silicate, chromate, fluoride and natural organic matter (NOM), i.e., humic acid (HA), showed the highest effect of phosphate on the decrease of arsenate adsorption. Time-dependent adsorption was best described by pseudo-second-order kinetic model and Weber-Morris model which predicted intra-particle diffusion as a rate-controlling step. Also, activation energy (E-a/kJ mol(-1)): 8.85 for Cd2+, 9.25 for Pb2+ and 7.98 for As(V), were obtained from kinetic data.

AB  - Metastable nanopowder ZnTiO3 was pressed into cylindrical compacts at 200 MPa. Compacts were treated by conventional heating with isothermal holding at 931 degrees C for 10 minutes, 25 minutes and 40 minutes. ZnTiO3 compacts were also heated with a two-step sintering schedule with maximal 913 degrees C and isothermal holding at 896 degrees C, for approximately the same holding times as the isothermal schedule. Shrinkage during heating was monitored with a dilatometric device, while microstructure was determined with atomic force microscopy. XRD patterns were collected for the most interesting samples. Microstructures of sintered specimens showed differences introduced during the last sintering stage by the two different heating schedules. Goal of the presented work was to discuss the possible sintering mechanisms for the two step sintering schedulle according to the presented results.

AB  - Structural changes caused by mechanical activation of SrTiO3 powders were investigated using a variety of methods. Average crystallite size continuously decreased with increased activation time to around 20 nm after 120 min activation, while mesopore volume and specific surface area increased accordingly. Higher activation times lead to increased agglomeration of nanoparticles to form agglomerates of around 2 mu m in size, ultimately producing a relatively stable powder, which exhibits lower microstrain than powders activated for shorter periods of time. Raman spectroscopy shows that the behavior of TO2 and TO4 modes is consistent with a decrease in particle size, while behavior of the nonpolar TO3 mode is markedly different, indicating relaxation of the inversion symmetry in polycrystalline SrTiO3. UV-VIS spectra show that mechanical activation has negligible effect on SrTiO3, with a slight shift caused by TiO2 contamination due to presence of air. Other than this, the mechanical activation process preserves the chemical purity of the initial powder.

AB  - A new Ni(II) complex, [Ni(L)(H2O)] (1), with diethyl 3,3'-(2,2'-(1,1'-(pyridine-2,6-diyl) bis(ethan-1-yl-1-ylidene)) bis(hydrazin-1-yl-2-ylidene)) bis(3-oxopropanoate) ligand (H2L) was synthesized as a potential chemotherapeutic agent. Polidentate ligand was coordinated to Ni(II) NNN-tridentately, in dianionic form, while monodentate water coordination completed square-planar geometry around metal. Structure in the solution was determined by NMR spectroscopy and the same coordination mode was observed in the solid state using IR spectroscopy and further verified by DFT calculations and electrochemical studies. Thermal stability of 1 was determined in both air and nitrogen atmosphere. Anticancer activity of 1 was investigated on acute monocytic leukemia (THP-1) and pancreatic adenocarcinoma (AsPC-1) cell lines. On THP-1 cells 1 induced powerful apoptotic response (ED50 = 10 +/- 3 mu M), which was revealed to be only partially caspase-dependent, with activation of caspase-8 as the dominant course. This suggested that experimentally validated covalent binding of 1 to DNA is not the only mechanism responsible for programmed cell death. This was supported with experiments on AsPC-1 cells. Although treatment of those cells with 1 resulted in poor apoptotic response, cell cycle changes showed concentration-dependent shifts indicating a dual mechanism of activity. This study also reviews the results of preliminary biological screening, which demonstrates that 1 displays a unique pattern of anticancer activity with at least two mechanisms involved.

AB  - Influences of the vinyl modified nanosilica Aerosil (R) 380, i.e., vinyl and methacryloyl silane coupling agent and linseed oil fatty acids (BD) reactive residues, on the mechanical properties of the unsaturated polyester resins (UPes) based nanocomposites, was studied. The polycondensation of maleic anhydride and products of poly(ethylene terephthalate) (PET) depolymerization with propylene glycol, with and without separation of ethylene glycol, yields UPe1 and UPe2 resin, respectively. The hydroxyl terminated PET depolymerization products (glycolyzates) and UPes were characterized by acid and hydroxyl values, Fourier Transform Infrared (FTIR) and nuclear magneti resonance (NMR) spectroscopies. Transmission electron microscopy (TEM) confirmed that silica nanoparticles formed domains of aggregates in the polymer matrix. An increase from 195 to 247% of stress at break (sigma(b)), and from 109 to 131% of impact strength (sigma(i)) of UPes based nanocomposites was obtained for 1 wt% addition of vinyl modified silica. Flexural strength (sigma(f)) increase from 106 to 156% for both UPes based nanocomposites with 1 wt% addition of BD modified silica. Cross-linking density (nu), storage modulus (G'), tan delta and T-g of the nanocomposite were determined from the dynamic mechanical testing and discussed in relation to the structure of silica modification.
