POLYMER-INORGANIC MATERIALS ON THE BASIS OF TETRAETHOXYSILANE

The paper is concerned with 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 polymerisation of diacrylate polymerising composition in the presence of sol gel system. The kinetic parameters of the process of photoinitiated polymerisation of diacrylate composition were determined depending on gelation time, composition of polymerising system and 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.
