本研究利用溶膠凝膠法製備矽氧烷複合材料，利用不同矽氧烷前驅物Tetraethyl orthosilicate（TEOS），Methyltriethoxysilane (MTES)及3-glycidoxypropyltrimethoxysilane(GPTMS），依照不同實驗條件加入有機高分子單體Tripropylene Glycol Diacrylate(TPGDA)，2-Hydroxyethyl methacrylate(HEMA)，以及poly(oxyethylene)(PEG)，探討其中的光學性質以及模擬分子鏈與透明度的關聯性。複合材料由傅利葉轉換紅外線光譜儀（FTIR）分析其結構；由UV-vis量測光穿透率。實驗結果發現複合材料因共價鍵結Si-O-Si的產生，使整體成為共聚合的形式，無機/有機物質相容性提高，使得複合材料透明度增加。

In this study, we attempted to prepare oxysiloxane composites by sol-gel method. We determined using different oxysiloxane, Tetraethyl orthosilicate(TEOS), Methyltriethoxysilane (MTES) and 3-glycidoxypropyltrimethoxysilane(GPTMS), in accordance with different experimental conditions, adding organic polymer monomer Tripropylene Glycol Diacrylate (TPGDA) , 2-Hydroxyethyl methacrylate (HEMA), poly(oxyethylene)(PEG), and discuss the optical properties and the relationship between molecular chain and transparency. The characterization of composites by Fourier transform infrared spectroscopy (FTIR) to analyze its structure, the transparency of the composites film is analyzed by UV-vis spectra. The experimental results show that the composite is co-polymerized Si-O-Si structure due to the covalent bond. Increased compatibility of inorganic / organic materials therefore increased the transparency of the composites.
