organic-inorganic composite

The influence of composition of hybrid organic-inorganic composites based on oligoesteracrylate (MGF-9)−tetraethoxysilane (TEOS) system on their thermal properties and molecular structure was investigated. Thermograms and curves of thermal destruction of samples were obtained, from which temperature ranges, weight loss of samples and thermal effects of each stage were defined. It is shown that introducing an inorganic filler into polymer matrix promotes increasing of thermal stability of the material.

Organic-inorganic materials have been synthesized by photoinitiated copolymerization of monomers: acrylonitrile, acrylamide and 3-sulphopropyl acrylate potassium salt in the presence of sol-gel systems based on tetraethoxysilane. Thermal stability, water uptake and ion-exchange capacity of obtained materials have been determined. Undertaken studies may be used for development of protonconductive membrane for fuel cells.
