本研究利用溶膠凝膠法(Sol-Gel)製備ZnO 微球顆粒,並將其運用於濕式化學法中之浸塗法(Dip-Coating)來製備撥水薄膜,此乃借由撥水液中氟烷基矽烷(FAS)、聚二甲基矽烷(PDMS)和ZnO 微球顆粒與玻
璃基材間複雜的水解及縮合反應,而使玻璃基板表面擁有粗糙微結
構、UV 光吸收和具低臨界表面張力-CF3 官能基之複合撥水薄膜。
本實驗旨在研究溶膠凝膠法(Sol-Gel)製備ZnO 微球顆粒的結構與特性之探討。選用適當前驅物含量,針對反應溫度與母液添加量等相關溶膠凝膠製程參數進行一系列分析探討。最後嘗試添加不同重量
百分比的ZnO 微球顆粒於撥水液中,利用水解及縮合反應製備複合
撥水薄膜,以期改善撥水薄膜之撥水性能、光學穿透率與強度,有利日後於撥水玻璃之應用與研究。
使用浸塗法(Dip-Coating)技術製備而得之含ZnO 微球顆粒撥水薄膜經SEM、AFM、UV-VIS 光譜、接觸角、鉛筆硬度計與往復磨耗測試機等測試,結果顯示薄膜表面均勻性、光學性質、撥水性能、強度與耐磨耗性已有相當成果,含ZnO 微球顆粒撥水薄膜可提升接觸角15o、光學穿透率達到80%以上、有局部吸收UV 之功能並能維持薄膜9H 之硬度。
