TiO2-based materials modified with methyltriethoxysilane (MTES) have been synthesized by sol-gel method and deposited onto glass substrates in order to obtain TiO2-SiO2 thin films. The effect of MTES on formation of TiO2-based materials was investigated by FTIR and UV-Vis spectroscopy, TGA analysis, TEM and contact angle. FT-IR spectra of obtained materials demonstrated that the silane reacts via a cross-link and covalently bond on the TiO2 surface. The high contact angle values were obtained for coatings coverage with materials modified with MTES and indicate that the functional Si-CH3 groups and TiO2 nanoparticle form a protective layer at the coating`s surface..
