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  - TiO2 nanoparticles, obtained by acid catalyzed hydrolysis of titanium isopropoxide, were surface modified by three gallic acid esters with different hydrophobic part length: octyl, decyl and lauryl gallate, and then used to prepare TiO2/epoxy nanocomposites. The characterization of the surface modified TiO2 nanoparticles was performed by FTIR and UV-Vis spectroscopy. The influence of different gallic acid esters and content of modified TiO2 nanoparticles on the glass transition temperature (Tg), rheological, barrier and mechanical properties of the nanocomposites was investigated by DSC, DMA, water vapor permeability test and König pendulum. The presence of the surface modified TiO2 nanoparticles in epoxy resin caused the increase of Tg and decrease of the water vapor permeability. However, the length of the nonpolar gallate part showed no effect on Tg of the synthesized nanocomposites, while the increase of the nanofiller content resulted in the increase of Tg. With increasing the hydrophobic part chain length of gallate ligand, the water vapor transmission rate decreased, while the hardness of the nanocomposites did not change.

AB  - The influence of alkyl gallate surface modified TiO2 nanoparticles on the
rheological properties of long oil alkyd resin, based on soybean oil, was
investigated. Surface modification of TiO2 nanoparticles, obtained by acid
catalyzed hydrolysis of titanium tetraisopropoxide, was performed with
propyl, lauryl or cetyl gallate. The average particle size and the crystal
structure of synthesized nanoparticles were estimated by transmission
electron microscopy and X-ray diffraction. The gallate chemisorption onto
surface of TiO2 nanoparticles was confirmed by FTIR and UV spectroscopy.
The examined dispersions were prepared by the addition of modified TiO2
nanoparticles to the commercial alkyd resin. The viscosity of the prepared
dispersions was higher than viscosity of the pure resin and it increased with
increasing length of hydrophobic part of the gallate used for surface
modification of TiO2 nanoparticles. This occurred because the increase of
their hydrodynamic volume led to the increase of the effective volume
fraction of particles in dispersion.

AB  - Spherical TiO2 particles of different size were dispersed in alkyd resin based on soybean oil. Four samples of TiO2 particles were used, three commercial and one obtained by acid catalyzed hydrolysis of titanium tetraisopropoxide. The size of the synthesized nanoparticles was determined by transmission electron microscopy. Surface modification of TiO2 nanoparticles was performed with propyl gallate and lauryl gallate. The influence of the size of TiO2 nanoparticles, their concentration and type of the surface modification on the rheological properties of alkyd resin was investigated. The obtained results have shown that the viscosity of the prepared dispersions was higher than the viscosity of the pure resin, increases with decreasing particle diameter and decreases with frequency increase. Surface modified particles showed higher influence on the viscosity of alkyd resin than unmodified, because their hydrodynamic volume is higher due to the presence of the adsorbed gallates, leading to the increase of effective volume fraction of particles in dispersion. For the lowest TiO2 concentration, the viscosity was higher for the sample modified with lauryl gallate, due to the higher thickness of the adsorbed layer. The increase of concentration, because of less dispersion stability of the particles modified with propyl gallate, leads to particle agglomeration. The presence of agglomerates, which was confirmed by a change in the slope of the functional dependence of storage modulus on loss modulus, leads to a rapid increase in viscosity.
AB  - Sferne čestice TiO2 različitih veličina dispergovane su u alkidnoj smoli. Površinska modifikacija nanočestica TiO2 izvedena je propil galatom i lauril galatom. Ispitivan je uticaj veličine nanočestica TiO2, koncentracije, kao i vrste površinske modifikacije na reološka svojstva alkidne smole. Dobijeno je da je viskoznost pripremljenih disperzija veća od viskoznosti čiste smole, da raste sa smanjenjem prečnika čestica i opada sa povećanjem frekvencije. Površinski modifikovane čestice imaju veći uticaj na viskoznost alkidne smole nego nemodifikovane zbog povećanja efektivnog zapreminskog udela čestica u disperziji. Za najmanju koncentraciju TiO2 viskoznost je veća kada je modifikacija izvršena lauril galatom, dok sa povećanjem koncentracije, zbog manje disperzione stabilnosti čestica modifikovanih propil galatom, dolazi do njihove aglomerizacije i naglog povećanja viskoznosti.

AB  - Incorporation of surface modified TiO2 nanoparticles into polystyrene (PS) matrix was achieved by in situ bulk radical polymerization of styrene. The surface of TiO2 nanoparticles was modified with four amphiphilic esters of the gallic acid (octyl, decyl, lauryl and cetyl gallate), which have different lengths of hydrophobic alkyl chain (C8C16). FTIR and UV-Vis spectroscopy measurements confirmed the formation of a charge transfer complex between surface Ti atoms and gallic esters. Microstructural characterization of the synthesized nanocomposites revealed that the best dispersion of TiO2 nanoparticles in PS was achieved when the TiO2 surface was modified with octyl gallate. The presence of surface modified TiO2 nanoparticles by different alkyl gallates does not have an influence on the molecular weight and glass transition temperature of PS matrix. On the other hand, thermal and thermo-oxidative stability of PS were significantly improved by incorporation of surface modified TiO2 nanoparticles. The most pronounced improvement of thermal and thermo-oxidative stability was observed for TiO2 nanoparticles surface modified with octyl gallate. POLYM. COMPOS., 2013.
