摘要

近年來有機無機混成材料的研究相當多，這類的研究是將兩種不同的材料結合，而這些混成材料經塗佈後利用紫外線硬化化方式而達到薄膜狀態。紫外光硬化官能基分為壓克力反應的自由基系和環氧基反應的陽離子系統兩種。薄膜型之有機無機混成材料有較佳的光學及機械性質，自由基及陽離子兩硬化方式有不同的優點，自由基硬化則有快速硬化的優點，陽離子硬化則具有較佳的附著性。因此本實驗旨在合成多官能性之光硬化材料，藉由溶膠-凝膠 (sol-gel) 法合成具有無機物性質，含自由基和陽離子兩種硬化官能基的寡聚物混成材料，而探討2-(3,4-epoxycyclohexyl) ethyltrimethoxysilane (ECEMS)、 methacryloxypropyl -trimethoxysilane (TMSPMA) 和壓克力單體 2-hydroxyethylmeth-acrylate (2HEMA)經sol-gel反應後得到有機-無機寡聚物之混成材料，塗佈後經紫外線硬化成膜後物理性質的變化。

There are numerous researches conducted in the past decades centering on organic-inorganic hybrid materials to explore this advanced technology, most of the literatures are confined on combining two different functional into a oligomer, these oligomeric hybrid materials were then coated and cured via UV light into a film.
There are two well known UV-induced curing methods, free radical and cationic. The free radical has the advantage of fast cure but suffering from poor anchorage while the cationic has better anchorage but the cure is sluggish. To get a fast cured / good anchorage UV-cured oligomeric hybrid materials, the epoxy and acrlyate functional groups are incorporated into a hybrid molecule via sol-gel method to obtain a dual-cured material.
A series of organic-inorganic oligomeric materials were synthesized through sol-gel process using 2-(3,4-epoxycyclohexyl) ethyltrimethoxysilane (ECTMS)、 methacryloxypropyl-trimethoxysilane (TMSPMA) and acrylic monomer, 2-hydroxyethylmeth-acrylate (2HEMA), the synthesized materials were then coated and cured through UV light to obtain filmic materials. The related physical and chemical properties of these brand new materials were also explored.
