Preparation and Characterization of Epoxy Acrylate/ Mesoporous Silica Composite Materials

Abstract

Mesoporous silica was prepared by sol-gel method. TEOS was the resource of inorganic materials and EO₂₀PO₂₀EO₂₀ (P123) as template. The structure of mesoporous silica was tested by SEM and TEM. The diameter of mesoporous silica was 500 nm and the length was about 1μm. The diameter of pore path was approximate 5 nm. The BET area was 492 m²g^-1 and the pore volume was 1.009 cm³g^-1 via the experiment of nitrogen adsorption-desorption. Mesoporous silica was uniformly dispersed in epoxy acrylate resin. EA/mesoporous silica begun evident weight loss at 325 ºC, 25 ºC higher than pure epoxy acrylate resin.
