碩士 === 國立勤益技術學院 === 材料與化學工程研究所 === 94 === The aim of this thesis is to synthesize the optical thin film for hydrophobic and abrasion-resistant inorganic/organic hybrid materials. The copolymer of poly(MMA-co-MPTS)-colloid silica were synthesized by using the free radical polymerization of the methyl methacrylate (MMA) with γ-methacrylate propyltriethoxysilane(γ-MPTS). Furthermore we hydrolyzed the above copolymer with tetraethoxylsilane (TEOS), fluoroalkylsilane (FAS) and colloid silica on the weak acid condition by a sol-gel process to obtain the optical thin film of hybrid material of poly(MMA-co-MPTS)-colloid silica. On the sol-gel reaction proceeding, the covalent bond was formed between organic phase and inorganic phase. Moreover, the effects of the colloid silica content on the optical properties, abrasion-resistant, morphology and thermal stability of the hybrid thin films were discussed in this thesis. The advantage of our purposed method is the optical thin film being the good optical property, abrasion-resistant, and thermal stability in comparison with the optical thin film without colloid silica. The other merit is the surface of our thin film having the good properties of surface roughness and hydrophobic because of fluoroalkylsilane and colloid silica coexisted in the surface of our purposed method.
