摘要

本文屬超疏水薄膜製作，其以乙醯丙酮鋁、矽或水鋁礦為超疏水結構之基礎材料，分別以不同比例加入乙醇形成溶液之後再將其塗佈於聚四氟乙烯薄膜上，並於塗佈後以240~260℃的溫度進行處理，此主要是藉由AACA於102℃時會開始產生昇華作用而獲得奈米孔洞的表面，最後再以氟素單體在表面產生縮合聚合，以獲得薄膜表面之穩定超疏水性質。

The paper is to manufacture the nano super-repellant film. The aluminium acetylacetonate (AACA) and boehmite or silica were employed as a base coat material to form an irregular nano surface structure. They were first dissolved in ethanol with different weight ratios of AACA and boehmite, coated on the surface of teflon and finally heat treated at 240-260℃. The purpose of heat treatment is to remove the AACA part of the film to form a nano size voids of 30-100nm (nano layer). The size of nano voids were varied with heat treatment temperature and time. After that, the nano layer was then coated with heptadecafluorodecyltrimethoxy silane monomer with water for hydroxylation and then condensated at 140℃, 1h to form poly-condensation layer (water and oil repellent layer).
