本論文之目的是製備具有耐磨耗性與表面疏水性之有機-無機混成材料之光電鍍膜材料。 本研究首先使用帶有triethoxysilane group的矽氧烷交聯劑(γ-methacrylate propyl trimethoxysilane, γ- MPTS)與丙烯酸單體(methyl methacrylate, MMA)以自由基聚合反應方式,形成共聚合物。更進一步利用共聚合物鏈上的矽氧烷官能基團與加入的tetraethoxylsilane(TEOS)、fluoroalkylsilane(FAS)與colloid silica在酸性條件下進行溶膠-凝膠反應,在反應過程中有機相與無機相間會形成共價鍵結合,以製備出poly(MMA-co-MPTS)-colloid silica之光學鍍膜材料。更進一步,本論文也探討二氧化矽凝膠粒子對材料之光學性質、耐磨耗性質、表面性質及熱穩定性之影響。
本論文所提出光學鍍膜製備方法之優點與未添加凝膠粒子方法比較,本論文方法對材料之光學性質、耐磨耗性質、及熱穩定性皆有明顯提升。 本論文方法之另一優點是由於鍍膜表面具有氟素官能基團及二氧化矽凝膠粒子,使鍍膜本身具有較佳之表面粗糙度與疏水性之特性。
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.
