本研究採用溶膠凝膠法製備無機/有機混成材料,利用Tetraethyl orthosilicate(TEOS)及2-Hydroxyethyl methacrylate(HEMA)形成無機前驅物後,依照實驗條件加入有機聚合物單體(TPGDA),並在其中添加不同側鏈官能基的多立面無機矽氧烷寡聚體(POSS)進行反應。複合材料由傅利葉轉換紅外線光譜儀(FTIR)分析其結構,熱重分析儀(TGA)測定其熱性質,UV-vis量測光穿透率,並以鉛筆硬度機測其表面硬度。實驗結果發現複合材料因共價鍵結的產生,使整體成為共聚合的形式,無機/有機物質相容性提高,使得複合薄膜光穿透度可以達90%以上,且熱性質和表面硬度隨Si-O-Si網狀結構含量的增加有所提升。而添加多立面無機矽氧烷寡聚體複合系材料,因POSS特殊的立體結構,可以有效提升光、熱及機械性質,並因POSS側鏈官能基和複合材料形成共價鍵結,使膜材特性因側鏈官能基的不同而得到改變,可提升膜材的應用性。
In this study, we attempted to prepare inorganic/organic hybrid materials by sol-gel method. We determined using of Tetraethyl orthosilicate(TEOS) and 2-Hydroxyethyl methacrylate(HEMA) formation of inorganic precursors, in accordance with the experimental conditions, adding organic polymer monomer and functional Polyhedral-Oligosilsesquioxanes(POSS) for reaction, use of covalent bonding hybrid materials can enhance the stability of film. The characteristization of hybrid materials by Fourier transform infrared spectroscopy (FTIR) to analyze its structure, thermal gravimetric analysis (TGA) to determination of thermal properties. The transparency analysis of the hybrid fime by UV-vis spectra, and pencil method to testing the surface hardness. The experimental results show that the formation of SiO2 nano-particles average to disperse in the film, let the hybrid film making degree of light transparency more than 90%, thermal properties and surface hardness increased with the inorganic content. Functional Polyhedral-Oligosilsesquioxanes hybrid materials, because of its special three-dimensional structure can effectively enhance the light, heat and mechanical properties.
