Properties of Organic/Inorganic Hybrid Material Synthesized from Acrylic Resin and Silane-Terminated CS

Organic/inorganic hybrid materials synthesized from acrylic resin and silane-terminated colloidal silica(CS). The silane-terminated CS was prepared in variation with the kind of silane to CS. The CS treated with methyltrimethoxysilane(MTMS) and then treated with vinyl trimethoxysilane(VTMS), 3-glycidoxypropyltrimethoxysilane(ATMS) or 3-methacyloxypropyl trimethoxysialne(ETMS) by sol-gel method, respectively. The variation of silane-terminated CS and acrylic resin were hybridized by thermal-polymerization. Thin films of organic/inorganic hybrid materials were prepared using spin coater on the glass and aluminum sheets. Their contact angle, surface electric resistivity and thermal resistance improved with the amount of silaneterminated CS. The contact angle and surface electric resistivity of hybrid thin film with VTMS were enhanced. The surface of hybrid thin film with VTMS was homogeneous through FE-SEM.
