Abstract:	本研究係以溶膠-凝膠法於低折射的壓克力系UV膠中加入不同含量(30wt%、40wt%及50wt%)ZnO前趨體溶膠，接著在乾淨玻璃基板上旋鍍成濕膜，經由紫外光固化及不同乾燥溫度(250℃、275℃及300℃)醇解，得到透明之ZnO/UV膠薄膜。奈米ZnO顆粒均勻分散在UV膠基材中且平均顆粒大小約在40nm-80nm。另外，使用商用奈米ZnO顆粒以機械分散法加入壓克力系UV膠中，作為溶膠-凝膠法之對照組，實驗結果顯示機械分散法之ZnO顆粒在UV膠中團聚嚴重。本研究同時探討ZnO/UV膠薄膜在不同ZnO顆粒含量及乾燥溫度對薄膜之光學性質影響。實驗結果在300℃乾燥溫度及50wt%ZnO的含量，折射率從UV膠的1.63增加至1.72，且可見光透光率均高於50%。另外，從FTIR分析得知奈米ZnO顆粒和UV膠沒有化學式的鍵結存在。 A UV curing acrylic resin /nano scaled meter zinc oxide hybrid films with tunable optical properties were prepared by means of the sol-gel synthesis method. The ZnO precursor solution which includes different weight ratios(30wt%、40wt%及50wt%) mixed with the UV curing acrylic resin through the way of sol-gel，and then this synthesis generates transparent hybrid films via the process of make a wet thin film by deposition on spotless glass substrate，ultraviolet curing and desorption treatment at different drying temperatures (250℃、275℃and 300℃). The approximately 40nm-80nm zinc oxide uniformly distributes over a matrix and FTIR analysis show no existence of chemical bodings between zinc oxide and UV curing acrylic resin。The refractive indices of these molecular hybrid films are much higher than that of UV curing acrylic resin e.g., at a ZnO loading of 30 wt % under at 300℃desorption treatment, the resulting molecular hybrid film exhibits a measured refractive index of 1.72 compared to that of 1.63.Additional, the cut-off wavelength of transmittance at ultraviolet wavelength range in the hybrid films shifted to the long wavelength side.
