Obtaining and properties of epoxy-silica composites.

Abstract

The master’s thesis deals with the problem of obtaining of organic-inorganic based on epoxy resin EPONEX 1510 and tetraethoxysilane using sol-gel technology. The optimal schedule of curing of polymer and composites was established. The yield of the sol fraction and the glass transition temperature of the obtained composites were determined. It was shown that with the increasing of silica content the crosslinking density and glass transition temperature of composites decreases. The obtained materials are resistant to aggressive media: the equilibrium degree of swelling in 10 % nitric solution and in 20 % sulfuric acid solution does not exceed 2 %.
