本論文以紫外光聚合法合成高透明的壓克力高分子與中孔洞氧化矽複合材料。中孔洞氧化矽材料具有熱穩定性佳、孔洞大、薄膜厚度厚的優點，而壓克力高分子具有高透明、不黃變、成型容易、韌性高、硬化快速及省能源等優點。本研究的主要目的為結合此二種有機/無機複合材料的優點，並改善其衍生出的缺點，如混濁、沉澱，藉以合成出高透明光學材料。因其兩者材料之間，仍存在著不同材料間的差異，如：有機高分子的分子結構、中孔洞氧化矽型態學，以及有機/無機複合材料間的折射率差異。
本研究以Lorentz-Lorenz有機/無機複合材料之折射率公式作為理論基礎，並設計實驗，分別改變不同壓克力官能基的分子結構，去改善有機/無機複合材料間的透明度的問題。在合成無機物方面，利用中性界面活性劑作為有機模板，並利用其自組裝的方式（self- assemble），再藉由矽酸鈉的聚合作用，使無機物再逐漸地附著上去。本實驗以嫁接-萃取法，利用帶有甲基丙烯酸甲酯基的矽烷化合物對中孔洞氧化矽表面上的Si-OH作修飾，並利用乳化聚合法增加壓克力的矽烷化合物的側鏈分子結構，得到SiO2/Silane/MMA的比在1/2/6的透光性最好。
此外，本實驗利用總體聚合法（Bulk polymerization）使壓克力單體與中孔洞氧化矽作預聚合（prepolymer），再利用紫外光聚合方式合成高透明的有機/無機混成材料，約15-30 min即可快速硬化，以符合工業上大量且快速生產的需求。
本實驗分別改變不同的界面活性劑種類與濃度、甲苯添加量、pH值、矽酸鈉的添加量，來探討中孔洞氧化矽型態的變化對透明度的實驗結果影響，發現當選擇的三塊狀共聚高分子中性界面活性劑P123（EO20PO70EO20）的EO/PO值在0.07~1.5，而甲苯-界面活性劑-水的HLB值的比例在8-14的範圍，在pH=5.0，40℃之條件下反應，再經由水熱100℃所得到的中孔洞氧化矽材料，結構最均勻，透光性最好，與壓克力的分子結構為直鏈型單官能基的MMA所得到的有機/無機複合材料的透明度最佳，並解決混濁、沉澱等問題。
本實驗結果以穿透式電子顯微鏡、氮氣吸附/脫附曲線來獲得中孔洞氧化矽的型態與表面積等資料。並以傅立葉氏紅外線光譜儀（FTIR）、微分掃瞄卡計（differential scanning calorimeter）作探討，以獲取高透明有機/ 無機材料之物性資料。

In this thesis, we studied on the synthesis of the transparent acrylic polymer/mesoporous silica hybrid composite. The mesoporous silica materials possess excellent thermally and mechanically stability, high surface area and large high pore size. Acrylic polymer has many advantages, such as highly transparent, weather resistance, highly flexibility and fast curing. The purpose of this research is to propose a new synthetic method for the synthesis of optically transparent organic-inorganic composite. The organic-inorganic composites should possess both advantages of organic acrylic polymer and inorganic mesoporous silica composites.
Based on concept of Lorentz-Lorentz organic/inorganic refractive index equation, we proposed the experimental approach to prepare the proper acrylic molecular structure wit the refraction index close to that of silica. On the other hand, we synthesized mesoporous silica foams by using toluene/neutral surfactant o/w emulsion as templates, and sodium silicate as silica source. After a silicate condensation and self-assembling at pH  5.0, the mesoporous silica foams were readily prepared. To introduce chemical bonds between the mesoporous silicas and acrylic polymers, we modified the mesoporous silica surface Si-OH with the methacrylate group silane. For increasing the chain length of the acrylic polymer anchored on the mesoporous silica, the methacrylate-modified mesoporous silica was reacted with a proper amount acrylic monomer in ethanol solution. The 1SiO2/2silane/6MMA component is most favorable for the preparation of transparent mesoporous silica-acrylic polymer composite. Then, the highly transparent acrylic polymer mesoporous silica nanocomposite was obtained with a bulk copolymerization of the 1SiO2/2silane/6MMA component in acrylic monomer under the ulta-violate radiation.
In our experiments, we studied the effects of the surfactants and surfactant concentration, pH value, different silica/toluene/water composite to study the mesoporous silica morphologies how to effect the transparent of acrylic polymer/mesoporous silica nanocomposite.
In conclusion, we found that the tri-block surfactant P123(EO20PO70EO20) its property EO/PO = 0.07~1.5, the HLB value of surfactant/toluene/water = 8~14, pH=5.0, we get the uniform mesoporous silica foams. After surface modification, pre-polymerization and copolymerization the mesoporous silica foams were well-dispersed in the matrix of the linear single-functional-group MMA that is a highly transparent organic inorganic composite. The characterizations on the highly transparent acrylic polymer mesoporous /silica nanocomposite were obtained by FTIR, and differential scanning calorimeter.
