Based on (3-glycidoxypropyl)silsesquioxane (GSSO) derived from the hydrolytic condensation of (3-glycidoxypropyl)trimethoxysilane (GPMS), GSSO-containing polyimide hybrid films were prepared using the sol–gel process and spin coating. Nanoindentation tests were carried out to study the influence of GPMS in the hybrid films on nanomechanical properties before and after exposure to atomic oxygen (AO)...
PS/silica core/shell composites were synthesized by the modified Stöber method using polystyrene spheres and cetyltrimethylammonium bromide as dual templates under room temperature. The silicate species and the templates were self-assembled to form mesoporous silica shell on the surface of the PS spheres. Hollow silica spheres with mesoporous shell were obtained by removing the polymer core and the...
