摘要

本研究利用溶膠凝膠法(sol-gel method)製備無機/有機複合材料，利用乙基三乙基矽氧烷 (VTES)當作前驅物，依照實驗條件加入有機單體(2-hydroxythyl methacrylate ,HEMA)與高分子聚合單體(triproplyene glycol diacrylate, TPGDA)進行反應。無機/有機複合材料藉由傅立葉轉換紅外線光譜儀(FTIR)分析結構、熱重分析儀測定其性質和最大裂解溫度、電阻抗測量其大小以及鉛筆硬度測其硬度。實驗結果發現無機/有機複合材料因共價鍵的產生使整體成為共聚合物，大幅提升成膜的穩定性、熱性質以及表面硬度，並隨著無機/有機比例的增加而直接有所提升，更重要因VTES特有的官能基CH2=CH2大幅提升膜材的抗腐蝕效果，此類型的sol-gel method材料開發，利用UV曝光硬化，脫膜後保持微結構完整性，可大幅改良傳統奈米結構製程所產生的缺點。
添加多立面體無機矽氧烷寡具體複合系材料(POSS)，因POSS特殊立體網狀結構可以有效提高硬度，並利用Methacryl POSS側鏈官能基和複合材料形成共價鍵提高電阻抗以及抗腐蝕效果，大幅提升其應用性。

The study of using sol-gel method to prepare inorganic /organic composite material, use vinyl-triethoxysilane(VTES) prepare for corrosion protection, by experiment condition to add HEMA and organic polymer monomer(TPGDA).Inorganic / organic composite material be analyze its structure by FTIR,measurement its properties and temperature of maximum rate of degradation (Tmax) by TGA, also measure the resistance value and hardness.Experiment results discover that inorganic / organic composite material become copolymer because its covalent bond.Significantly improve the stability, thermal properties and surface hardness of film forming, It`s directly proportional to the ratio of inorganic / organic.The most important is the unique functional group CH2= CH2of VETS will increase corrosion protection with film. UV curing after solidification, film material will release clearly without cause any damage to the surface micro structure. This process can significantly improve the weakness of traditional nanostructure procedure.
Added POSS into our experiment, because its special three-dimensional network structure can enhance the hardness, and use Methacryl POSS mix our composite materials to produce covalent bond, raising resistance value and corrosion protection to enhance the applicability.
