Summary:A paper is concerned with a consideration of preparing of tetraethoxysilane based organic-inorganic composites using sol-gel method. Two approaches are used: synthesis of organic-inorganic materials via sol-gel process in polymeric matrix of poly(vinylidene fluoride) and during photoinitiated polymerization of diacrylate polymerizing composition in the presence of sol-gel system. Kinetic parameters of the process of photoinitiated polymerization of diacrylate composition were determined depending on gelation time, composition of polymerizing system and on the concentration of sol-gel process catalyst as well. Complex thermogravimetric and differential-thermal analysis of polymer-inorganic material was carried out to define its thermal characteristics. Proton conductivity of obtained materials was evaluated by impedance spectrometry.
