在本實驗中，由於可紫外光交聯硬化之Epoxy acrylate具有反應性之OH基，在Sn觸媒下（T-12）可與TEOS產生脫醇反應，因此產生Si-O-C得鍵結，在經由SOL-GEL法製備成有機-無機混成材料可產生良好之混成效果，經由SEM可觀察出SiO/sub 2/、粒徑大小10-20nm，可證實為奈米級複合材料，另外由TGA可證實SiO/sub 2/隨著TEOS增加而增加，薄膜硬度也隨之增加。 In this experiment, because of the UV-curable epoxy acrylate resinhave reactive OH group, it can be reacted under the Sn catalyst. Thenit can form the Si-O-C chemical bond, so it have good hybride effectby sol-gel process. They can be identified by SEM to mesure thepartical size. Their silica containe can increase by more TEOSconcentration, determined by TGA, and their silica can improve thethin film hardness.
