Epoxy-Silica Nanocomposites Based on Ethoxysilanes and Diglycidyl Ether of Dicyclohexylpropane
Sol-gel method was used to obtain epoxy-silica nanocomposites cured with dicarboxylic acid anhydride. Incorporation of filler into the system leads to plastisization of organic matrix: glass transition temperature decreases and sol-faction yield increases with filler content. At w(SiO2) = 0.5–3 mas % effect of low additions is observed: molecular weight of chain between junctions decreases and thermostability of hybrid materials rises.
