本計畫以末端基為胺基的3-胺基丙基三乙氧基矽烷(APTES)與含異氰酸酯為末端基之聚胺基甲酸酯預聚物反應，形成三乙基矽衍生物；此三乙基矽的衍生物可進行自身架橋的反應；再使用四乙氧基矽烷(TES28、TES40)、雙醇矽烷(Si-Diol)等，和三乙基矽衍生物進行架橋反應，並加入氧化矽作為填充物，製備出六種成品，將其分為三個系列來探討。探討重點在於評估架橋前後及加入氧化矽後之物理性質變化(如吸水及吸酒精性、膠含量、硬度等)、機械性質變化(如拉力測試)以及熱性質變化(如熱重分析)。 This article focused on organic-inorganic hybrid by using the non-solvent sol-gel process. The reaction between the amino group of 3-aminopropyl-triethoxysilane (APTES) and isocyanate groups of polyurethane prepolymer produced a self-curable derivative of APTES. The self-curable derivative of APTES was reacted with tetraethoxysilane (TES28 or TES40) or diol-containing silane (Si-Diol) to perform cross-linking reactions. The silica was also added in to play a role as the filler. Therefore, there were six kinds of products to be made out. The six kinds of products were divided into three series and discussed their changing in physical properties (water-uptake, ethanol absorption, and gel content and hardness et al.), mechanical properties (tensile strength), and thermal properties (thermal gravimetric analysis).
