AB  - Polyurethane networks (PUNs) based on hyperbranched polyesters (HBP),
polycaprolactone (PCL), and isophorone diisocyanate were prepared.1,2 PUNs consist
of different content of hard (HS) and soft segments (SS). The impact of the HBP and
the content of the SS on the structure and viscoelastic properties of the prepared PUNs
were investigated. XRD analysis confirmed that PUNs with lower SS content were
amorphous, while samples with the highest SS content had a certain degree of
crystallinity. Viscoelastic properties of PUNs depend on the SS content and used
HBP. These PUNs have potential application as coatings.

AB  - The influence of soft segment (SS) content on the properties of novel polyurethane networks (PUNs), prepared by a two-step polymerization in a solvent mixture, was investigated in this work. Hyperbranched polyester of the third pseudo generation (BH-30) was used as a crosslinker, and together with isophorone diisocyanate (IPDI) was applied to build hard segments (HS) in PUNs. On the other hand, SS of the prepared PUNs are based on polycaprolactone (PCL). The content of SS in PUNs varied from 10 to 50 wt%. The structural, thermal and mechanical properties, swelling behavior, as well as morphology of PUNs, were explored by various experimental methods. Performed investigations have shown that the use of BH-30 led to the emergence of relatively high crosslinking density and good mechanical properties, and that all features of PUNs significantly depend on the SS content. Higher PCL content caused presence of certain crystallinity, better thermal stability, more pronounced microphase separated morphology, but also lower degree of hydrogen bonding, crosslinking density and storage modulus of the prepared PUNs. The obtained results have shown that the properties of PUNs can be easily varied and customized to different practical needs.

AB  - The aim of this work was to examine the influence of polycaprolactone (PCL) as a soft segment (SS) on the surface properties of polyurethane networks (PUNs). Five PUNs with different SS content (from 10 to 50 wt%) were prepared using Boltorn® aliphatic hyperbranched polyester of the second pseudo generation and isophorone diisocyanate as components of hard segments. The structure, hydrophobicity, wettability, and swelling behavior of these PUNs were investigated. Primarily, the obtained results showed that properties of prepared PUNs strongly depend on the content of SS that is, PCL. It has been established that the increase of SS content reduced the degree of hydrogen bonding in PUNs. Also, the increase of the SS content in PUNs induced appearance of more pronounced microphase separated morphology, better hydrophobicity and non-wetting with diiodomethane. Simultaneously, the increase of the SS content led to the decrease of contact angles with formamide, and surface free energy of the prepared PUNs. These PUNs show good surface properties that are required for their potential application such as coatings.

AB  - The scope of the present study was to prepare fully bio-based unsaturated polyester resins (UPRs) with comparable properties to the commercial formulations. The focus was set on the determination of the optimal prepolymer formulation using the same set of diacids (itaconic and succinic acid) and different diols (propylene glycol, isosorbide and neopentyl glycol) or its equimolar mixtures, keeping the fixed molar ratio of 1:1:2.1 in all feed compositions. Instead of commonly used styrene, bio-based dimethyl itaconate was used as a reactive diluent (RD). The rheology of the obtained resins was studied in detail. The effect of the used diol on structural (FTIR), thermal (DSC), thermomechanical (DMA), and mechanical (tensile) properties was explained. The properties of UPRs were found to be highly dependent on the diol used in the prepolymer formulation. The UPR with an equimolar ratio of propylene glycol and neopentyl glycol was shown to be the most promising candidate to compete with the commercial petroleum-based resins.

AB  - In this study, unmodified TiO2 nanoparticles (NPs) and TiO2 NPs surface modified with lauryl
gallate were incorporated into polyurethane (PU) network, based on Boltorn® aliphatic
hyperbranched polyester of the second pseudo generation (BH-20) as crosslinking agent and
polycaprolactone (PCL) as soft segment (SS). The influence of the applied TiO2 NPs on viscoelastic
properties and thermo-oxidative stability of the prepared PU/TiO2 nanocomposites (NCs) were
investigated by dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA),
respectively. DMA results revealed that addition of unmodified and modified TiO2 NPs led to the
increase of glass transition temperature of SS, decrease of the glass transition temperature of hard
segments and crosslinking density of PU network. According to the obtained results, PU/TiO2 NC
loaded with TiO2 NPs surface modified with lauryl gallate has better thermo-oxidative stability than
pure PU and PU/TiO2 NC prepared with unmodified TiO2 NPs.

nanofiller. Morphology of clay nanoparticles and mechanical properties of PUNs were investigated
by XRD analysis and tensile test measurements, respectively. The obtained XRD results revealed
that clay nanoparticles were completely delaminated and well dispersed as intercalated or partially
exfoliated layers in the polymer matrix. XRD also confirmed that prepared PUNs have amorphous
character. Prepared PUNs have good mechanical properties, which allow them to be used for
different purposes, such as elastomers, coatings, adhesives, etc.

hyperbranched polyester of the second pseudo generation (BH-20) as crosslinking agent, and
unmodified and surface modified TiO2 nanoparticles (NPs). The surface modification of TiO2 NPs
was done with lauryl gallate. The chemical structure of the prepared PU/TiO2 NCs was studied by
Fourier transform infrared spectroscopy (FTIR), while their amorphous nature was confirmed by Xray diffraction (XRD). The influence of type and content of the applied TiO2 NPs on swelling
properties in toluene and tetrahydrofuran (THF) and on water absorption of the prepared PU/TiO2
NCs were investigated. The obtained results revealed that swelling behavior depends on the used
solvent, while percentage of absorbed water decreases with increasing content of TiO2 NPs and it is generally lower in NCs prepared with modified TiO2 NPs.

NCs were investigated. The obtained results revealed that swelling behavior depends on the used
solvent, while percentage of absorbed water decreases with increasing content of TiO2 NPs and it is generally lower in NCs prepared with modified TiO2 NPs.",

AB  - Waterborne polyurethanes (WBPUs) represent a class of polyurethanes (PUs), in which water is used as the dispersion medium, instead hazardous organic solvents. In this manner, the emission of volatile organic compounds is decreased, leading to the environmental preservation. Poly(dimethylsiloxane) (PDMS) has a lot of useful features, such as low glass transition temperature, Tg, low surface energy, excellent biocompatibility, high thermal and oxidative stability, which is why PDMS is often used in WBPU formulations. Siloxane-modified WBPUs exhibit the properties of both, PDMS and PUs. WBPUs based on PDMS have good surface properties, such as excellent hydrophobicity, chemical resistance and low surface energy. Because of these useful features, WBPUs based on PDMS can be used as coatings, adhesives, paints, etc. In this work, a series of WBPUs was synthesized via one-step polymerization method, without a chain extension step, using acetone and water as solvents and stannous octoate as a catalyst.

AB  - A series of novel waterborne polyurethanes (WBPUs) was synthesized using α,ω-
dihydroxypropyl poly(dimethylsiloxane) (PDMS), isophorone diisocyanate (IPDI), 2,2-bis-
(hydroxymethyl) propionic acid (DMPA) and triethylamine (TEA). Different DMPA/PDMS and
constant –NCO/–OH molar ratio have been applied for the synthesis of six different WBPUs,
without the usage of chain extension step. The structure-properties relationship was examined
with diverse experimental analyses. ATR-FTIR, 1H and 13C NMR analyses confirmed the
incorporation of PDMS parts inside polyurethane backbone and the successful preparation of
WBPUs. XRD analysis showed that all WBPUs are amorphous, without any kind of threedimensional
order. According to the conducted TG measurements, the incorporation of PDMS
increases thermal stability of WBPUs. DMA results confirmed the existence of microphase
separation, which was more pronounced in WBPUs with higher PDMS content. Contact angle
measurements with water confirmed good surface hydrophobicity of these WBPUs, which
originates from the high percentages of Si atoms present on the surface of WBPU films. Good
hydrophobicity originates from PDMS which has known to possess low surface energy and have
a high tendency to migrate on the surface of the WBPUs. The synthesis of these WBPUs represents
a more efficient and eco-friendly way for preparation of polyurethanes and they are good
candidates for application as coatings.

AB  - In this study, six waterborne polyurethanes (WBPUs) were synthesized based on α,ω-
dihydroxypropyl poly(dimethylsiloxane) (PDMS), isophorone diisocyanate (IPDI), 2,2-
bis-(hydroxymethyl) propionic acid (DMPA) and triethylamine (TEA). WBPUs were
prepared without a chain extension step and with various DMPA/PDMS molar ratios
(from 0.2 to 0.7). The mechanical features, particle size and particle size distribution, as
well as molecular weights of WBPUs were investigated by diverse experimental
techniques.
Tensile strength values were in the range from 4.03 to 6.33 MPa, and generally decrease
with decreasing PDMS content in WBPUs. This occurs due to the presence of lower
degree of microphase separation in WBPUs with lower PDMS content. On the other
hand, the incorporation of flexible PDMS led to an increase of elongation at break values
(from 0.4 to 58.6%) in WBPUs. The particle size of the prepared WBPU dispersions and
molecular weight of WBPU films decrease with increasing DMPA content. Particle sizes
of these WBPU dispersions are in the range from 91.4 to 232.3 nm, while the weight
average molecular weights (Mw) are in the range from 11900 to 15300 g/mol [1].
Prepared WBPUs are polymer materials with good mechanical features and suitable
particle sizes, which enable them to be used as coatings for different purposes.

AB  - This work was focused on the synthesis of polyurethane networks (PUNs) based on
polycaprolactone (PCL) as soft segment (SS) and Boltorn® aliphatic hyperbranched
polyester of the second pseudo generation and 4,4′-diphenylmethane diisocyanate
(MDI) as the parts of the hard segments (HS), by a two-step solution polymerization.
In order to find the best ratio between HS and SS to achieve good thermal
and mechanical properties, suitable hydrophobicity and morphology of the PUNs,
various experimental analyses were conducted. The obtained results revealed that
features of the PUNs highly depend on the PCL content. The increase in the PCL
content leads to the increase in thermal stability, hydrophobicity and appearance of
the microphase separation, but on the other side, it also leads to the decrease in storage
modulus in the rubbery plateau, crosslinking density and glass transition temperatures

polycaprolactone (PCL) as soft segment (SS) and Boltorn® aliphatic hyperbranched
polyester of the second pseudo generation and 4,4′-diphenylmethane diisocyanate
(MDI) as the parts of the hard segments (HS), by a two-step solution polymerization.
In order to find the best ratio between HS and SS to achieve good thermal
and mechanical properties, suitable hydrophobicity and morphology of the PUNs,
various experimental analyses were conducted. The obtained results revealed that
features of the PUNs highly depend on the PCL content. The increase in the PCL
content leads to the increase in thermal stability, hydrophobicity and appearance of
the microphase separation, but on the other side, it also leads to the decrease in storage
modulus in the rubbery plateau, crosslinking density and glass transition temperatures
of PUNs. This work shows that features of PUNs can be easily adjusted for
a specific application by careful selection of the SS and HS ratio.",

AB  - A series of environmentally friendly polyurethane (PU) networks based on polycaprolactone as soft segment (SS) and Boltorn® aliphatic hyperbranched polyester of the second pseudo generation as crosslinking agent was prepared by a two-step polymerization in solution. The chemical structure of the PU networks was analyzed by Fourier transform infrared spectroscopy, while XRD analysis revealed that these samples are amorphous. Swelling measurements, water absorption study, dynamic mechanical analysis, differential scanning calorimetry, thermogravimetric analysis, mechanical tests and scanning electron microscope revealed that, swelling behavior, hydrophobicity, thermal and mechanical features and morphology of PU networks show clear dependence on polycaprolactone content. The increase of the SS content induced appearance of the microphase separated morphology, increase of thermal stability, elongation at break, hydrophobicity and swelling ability in tetrahydrofuran and toluene, but at the same time it is responsible for the decrease of crosslinking density, glass transition temperatures, rigidity, tensile strength and Young’s modulus of PU networks. Scanning electron microscope images of the fracture surfaces of PU networks show that their surface is rough, irregular, with flake-like structure, where size of flakes increases with increasing SS content. These results indicate that by choosing adequate SS content, PU coatings with diverse features based on polycaprolactone and Boltorn® aliphatic hyperbranched polyester can be designed for appropriate and desired application

AB  - Alkyd resin/TiO2 nanocomposites (NC) were prepared from short oil alkyd resin and TiO2 nanoparticles (NPs) surface modified with in situ formed imine ligand, based on 3,4-dihydroxybenzaldehyde and oleylamine, or with three gallic acid esters. The short oil alkyd resin was synthesized from sunflower oil, phthalic anhydride, and trimethylolpropane. Unmodified and surface modified TiO2 NPs were examined by transmission electron microscopy. Rheological investigation revealed that prepared dispersions have higher dynamic viscosity than pure alkyd resin. Using different characterization methods it was obtained that NCs have similar thermooxidative stability as alkyd resin, lower glass transition temperature, better barrier properties, enhanced hardness, better chemical resistance, and lower adhesion to the metal, except in the case of NC prepared using TiO2 NPs surface modified with imine, which exhibited better adhesion to the metal than pure alkyd resin.

AB  - Polyurethane networks (PUN) represent versatile materials which are usually consisted of
different hard (HS) and soft segments (SS). They possess very good mechanical, thermal and surface
properties. Such properties originate from their different composition, chemical structure of the
crosslinking agent and molecular weights of the HS and SS [1].
In this work, series of PUNs was obtained by catalyzed two-step polymerization method in
the solvents mixture. The PUNs were based on polycaprolactone macrodiol that represents SS and
4,4'-diphenylmethane diisocyanate and Boltorn® hyperbranched polyester of the second pseudo
generation which were selected as the HS. Six PUNs were synthesized with different content of SS
(from 10 to 60 wt.%).
The structure and surface properties (morphology, swelling behavior and water absorption) of
the synthesized PUNs was examined in order to investigate these materials for potential application in
coatings.

AB  - Surface modification of titanium dioxide nanoparticles (TiO2 NPs) with the biologically active molecule pyridoxine hydrochloride (vitamin B-6) was found to alter the optical properties. Microstructural characterization involving transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis revealed that the anatase TiO2 NPs had a narrow size distribution with an average diameter of 45 angstrom. The absorption onset of the surface-modified TiO2 samples was red-shifted by about 0.4 eV compared to the unmodified particles. The mode of binding between vitamin B-6 and the surface Ti atoms was investigated by Fourier transform infrared spectroscopy (FTIR). From the Benesi-Hildebrand plot, the stability constant of the surface complex was found to be of the order 10(2) M-1. The experimental findings were supported by detailed quantum chemical calculations based on the density functional theory (DFT). Agreement was found between the experimentally measured absorption spectra of the TiO2 NPs surface-modified with vitamin B-6 and the theoretically calculated electronic excitation spectra of the corresponding model system.
AB  - Површинска модификација наночестица титан-диоксида (ТiО2) биолошки активним молекулима пиридоксин-хидрохлорида (витамин B6) доводи до промене њихових оптичких својства. Микроструктурна карактеризација синтетисаних наночестица ТiО2 која обухвата трансмисиону електронску микроскопију (ТЕМ) и дифракцију рендгенских зрака (XRD) показала је да наночестице анатаза имају уску дистрибуцију величина са средњим пречником од 45 Å. Праг апсорпције површински модификованих наночестица ТiО2 је за 0,4 еV померен ка већим таласним дужинама у односу на спектар немодификованих честица. Коришћењем FTIR спектроскопије утврђен је начин везивања
витамина B6 за површинске атоме титана. Константа стабилности површинског комплекса је одређена на основу Бенеси–Хилдебрандове (Benesi–Hildebrand) анализе и износи 3,0×102 М-1. Експериментални резултати су поткрепљени детаљним квантно-хемијским прорачунима заснованим на теорији функционала густине (DFT). Утврђен је висок ниво сагласности између апсорпционог спектра наночестица ТiО2 и теоријски добијеног електронског ексцитационог спектра одговарајућег модела.

Agreement was found between the experimentally measured absorption spectra of the TiO2 NPs surface-modified with vitamin B-6 and the theoretically calculated electronic excitation spectra of the corresponding model system., Површинска модификација наночестица титан-диоксида (ТiО2) биолошки активним молекулима пиридоксин-хидрохлорида (витамин B6) доводи до промене њихових оптичких својства. Микроструктурна карактеризација синтетисаних наночестица ТiО2 која обухвата трансмисиону електронску микроскопију (ТЕМ) и дифракцију рендгенских зрака (XRD) показала је да наночестице анатаза имају уску дистрибуцију величина са средњим пречником од 45 Å. Праг апсорпције површински модификованих наночестица ТiО2 је за 0,4 еV померен ка већим таласним дужинама у односу на спектар немодификованих честица. Коришћењем FTIR спектроскопије утврђен је начин везивања
витамина B6 за површинске атоме титана. Константа стабилности површинског комплекса је одређена на основу Бенеси–Хилдебрандове (Benesi–Hildebrand) анализе и износи 3,0×102 М-1. Експериментални резултати су поткрепљени детаљним квантно-хемијским прорачунима заснованим на теорији функционала густине (DFT). Утврђен је висок ниво сагласности између апсорпционог спектра наночестица ТiО2 и теоријски добијеног електронског ексцитационог спектра одговарајућег модела.",

AB  - The surface of anatase TiO2 nanoparticles was modified with in situ synthesized imine, based on 3,4-dihydroxybenzaldehyde and octadecylamine. The modified TiO2 nanoparticles were investigated using FTIR and UV-Vis spectroscopy, which confirmed the formation of the charge transfer complex between imine and surface of TiO2 nanoparticles by the reaction of surface Ti atoms with hydroxyl groups of a modifying agent. TiO2 nanoparticles modified with imine were further applied as a filler for the preparation of epoxy based nanocomposites. Thermal and mechani­cal properties of the prepared nanocomposites were examined using the dynamic mechanical analysis, differential scanning calorimetry, thermogravimetric analysis and hardness measurements. The obtained results have shown that modified TiO2 nanoparticles have no significant influence on the glass transition temperature and that they slow down thermo-oxidative degradation of epoxy resin in the first stage and increase hardness of the crosslinked epoxy resin.

AB  - Unsaturated polyester resin (UPe)-based nanocomposites and fumed silica Aerosil R812S, R805 and R816, and R200 modified with phenyl terminal group, R200NPh, were prepared. UPe resins were synthesized from maleic anhydride and products of glycolysis, obtained by polyethylene terephthalate depolymerization with dipropylene glycol in the presence of tetrabutyl titanate catalyst. The obtained unsaturated polyesters were characterized by acid, hydroxyl, and iodine values and by FTIR and NMR analysis. The microstructural analysis of the prepared nanocomposites, performed by using transmission electron microscopy, confirmed that silica nanoparticles formed chain-like aggregates in the polymer matrix. The presence of modified silica nanoparticles had no influence on the glass transition temperature and thermal stability of polyester matrix. The tensile modulus, stress at break, and hardness of cured products increased with increasing silica content. The impact strength of cured samples was not influenced by the silica content.

AB  - The optical characteristics of inorganic nanoparticles (NP) have been well known for quite a long
time and this knowledge has been applied for the creation of optically functional materials based
on these NPs and different polymers used as a processable matrix. Remarkable optical properties of
certain polymer nanocomposites (NCs), such as absorption (ultraviolet [UV] and visible), transparency,
color, high refractive index, fluorescence, luminescence, different nonlinear optical properties,
etc. are the reasons for such large interest of various researchers from different disciplines all
over the world in this type of material. In these materials, NPs improve optical properties, while a
polymer matrix is used to stabilize the size and growth of NPs (Beecroft and Ober 1997). Polymer
NCs, which show such intriguing optical properties, include NCs prepared from different polymers
and metal NPs, metal oxide NPs, carbon-based NPs (fullerenes, graphene, and carbon nanotubes) or
semiconductor nanocrystals (quantum dots), as well as NCs based on conjugated polymer matrices
and different inorganic NPs. Since polymer NCs are prepared by synergistic combination of polymers
and NPs, optical properties of these specific materials can be tailored by adequate selection
of the organic and inorganic building blocks with desirable properties and by simply changing the
portion of NPs introduced in the polymer matrix. This led to the rapid growth of the area of polymer
NCs’ possible applications, such as for optical detectors, solar cells, in optical amplification,
photovoltaics, biosensors, for waveguiding in integrated optical devices, as optical coatings, optical
switches, high refractive index devices, for encapsulation of light emitting diodes (LEDs), as lens
materials, etc.
Linear and nonlinear optical properties of polymer NCs depend on the optical properties of the
polymer matrix and applied NPs, as well as on other different parameters such as type, size, shape,
surface characteristics, concentration, and spatial distribution of NPs in the matrix. Therefore, in
order to fully understand optical properties of polymer NCs, it is necessary first to briefly describe
the most important optical properties of its constituents, that is, polymers and NPs.

AB  - Poly(aniline-co-(m-aminobenzoic acid)) was synthesized electrochemically at graphite electrode under galvanostatic conditions. Aqueous electrolyte for synthesis was consisted of HCl and different amount of aniline and m-aminobenzoic acid. The presence of the meta positioned carboxylic group in m-aminobenzoic acid influenced higher co-polymerization potential, different morphology and electrochemical behavior of copolymers compared to polyaniline. Electrochemical activity is achieved by proton exchange in neutral environment that can result in a faster charge/discharge process, which is in the case of PANI limited by slow anion exchange, making this material promising for consideration in super-capacitors and in biological system.

AB  - The synthetic procedures for preparation of free-standing and attached to polymer support surface modified TiO2 nanoparticles (NPs) with absorption extended into the visible spectral region due to charge transfer complex formation were developed. The one-step synthesis of colloids consisting of surface-modified TiO2 NPs is based on the reaction between titanium(IV) isopropoxide (TTIP) and lauryl galatte in nonprotic organic solvents (tetrahydrofuran, xylol, chloroform). The poly(GMA-co-EGDMA) copolymer decorated with surface-modified TiO2 NPs was obtained in two steps. First, copolymer was functionalized with dopamine and then treated with TTIP in organic solvent at slightly elevated temperature. Thorough microstructural and optical characterization of free-standing and attached to polymer support surface-modified TiO2 NPs was performed involving transmission electron microscopy as well as absorption and reflection spectroscopy. Infrared spectroscopy was used to understand coordination of ligands to surface Ti atoms. Photoredox chemistry of surface-modified TiO2 NPs attached to the polymer support was tested. Enhanced photooxidative ability of composite was demonstrated by degradation of organic dye crystal violet under visible light illumination, i.e., using photons with energy smaller than 2.75 eV. On the other hand, photocatalytic hydrogen production was used to demonstrate photoreduction ability of surface modified TiO2 NPs attached to the polymer support.
