Abstract

The structure of epoxy-silica nanocomposites prepared by the sol-gel method via the cationic polymerization of the organic component and anhydride curing was studied by small-angle X-ray scattering. In the presence of 1.5% silica in the epoxy polymer, mass-fractal aggregates of the inorganic component are formed. In the range of low and high concentrations of SiO2, microphase segregation with the separation of inclusions randomly distributed in the epoxy matrix occurs.
