Firstly, the APTMS coupling agent performs the silanol intermediates by hydrolysis in pH 4.0 ~ 5.0 acid solution and with some active Si-OH functional groups which could covalently coupled between organic matrices and inorganic colloid Al2O3. After mixing optimal amount of EEC organic resins and SR-238 acrylate monomer, the condensation coupling and free radical polymerization would performed and successfully prepared these thermal resistant and anti-electrostatic organic/inorganic nanocomposite materials. The chemical bonding formation and the best weight contents of reaction components are identified by FT-IR spectra. The thermal resistance, transmittance, surface resistane, and hardness of these nanocomposites are measured by TGA, photo-UV, surface resistant meter and hardness tester respectively. Experimental results show that these nanocomposites have 85% transmittance and the best Td value is 451.20℃ which is 151.82℃ and 75.76℃ higher than those of pure EEC epoxy resin and pure SR-238 resin respectively. The glass transition temperature is not detected below 200℃. The surface resistanes of EEC/SR-238/APTMS/colloidAl2O3 hybrid thin films are decreased from 5.02×1014 to 1.92×1010 Ω/cm2. The morphology structures of the hybrid thin films are estimated by SEM. The results show that the optical thin films are evenly distributed with inorganic colloid particles and the average particle size of these nanocomposites is about 45 ~ 85 nm.
