Abstract

Organic/inorganic composite materials consisting of polystyrene (PS) and silica (SiO2) were synthesized by the sol-gel process, using styrene monomer and methacrylic acid 3-(trimethoxysilyl) propyl ester (MAMSE) as precursors. Three styrene/MAMSE ratios by mol were prepared, namely PS/SiO2 = 80/20, 60/40 and 50/50. The copolymer precursors were then hydrolyzed and condensed to generate PS/SiO2 composite materials. The copolymer precursors and composite materials were characterized by FT-IR, DSC, TGA and SEM. It was found that thermal properties of composite materials were improved as silica content increased. The compatibility between organic polymer and inorganic particles mainly derived from incorporating the polymer matrix with the silica covalently. To investigate the distribution of silica and microphase separation in the hybrid matrix, the morphology of the fractured surfaces was observed by SEM image. The silica particles are uniformly dispersed in the copolymer matrix. These
results show that silica networks are restrained under molecular level in the PS-SiO2 hybrid copolymers.
