紡織品可經由處理與設計，使其具備疏水、疏油、自潔、自癒(self-healing)及化學穩定等功能性，進而發展防護性服裝、油水分離等各種應用，因此廣泛受到學術界和工業界的關注。本研究以環境友善的水性製程，將材料塗佈於紡織品，創造出對水及各種油體具不同疏液性質之織物，例如: 超疏水/疏油之雙疏表面以及超疏水/親油表面，且具有自癒、抗物理、化學特性。實驗採用簡單的一鍋(one-pot) 製程，選用水性鐵氟龍分散體 (PTFE DISP)、疏水改質二氧化矽奈米粒子 (HM SiO2)、1H, 1H, 2H, 2H-全氟癸基三乙氧基矽烷 (FAS-17) 及水性聚氨酯 (WPU) 為材料，利用雙尺寸粒子創造粗糙度，添加全氟矽烷降低材料表面能，以及水性聚氨酯用來改善耐久性。
實驗結果顯示，將PTFE DISP/HM SiO2/FAS-17/WPU溶液浸塗於紡織品，可得到超疏水及疏油織物，對表面張力大於27.1 mN/m的液體之接觸角大於97.3°，且具備自潔、自癒及耐久性，可應用於防護性服裝。而使用PTFE DISP/FAS-17溶液塗佈的織物則展現超疏水及親油性質，利用其對水及油體疏液性的差異，在油水分離應用上有發展的潛力。

The functional textile surfaces for various applications, such as protection garments and oil/water separation, have attracted a lot of interests in both academia and industry. Nowadays, waterborne coating systems are highly desirable because of high safety and non-environmental impact. In this work, using PTFE aqueous dispersion (PTFE DISP), hydrophobically modified silica nanoparticles (HM SiO2), 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane (FAS-17) and waterborne polyurethane (WPU) to form a stable, homogeneous waterborne solution. This coating solution was then applied onto the twill weave polyester fabrics. For textiles with a micro-scale fiber structure, nanoscale particles are coated onto the surface to create the hierarchical structure. The fluorination is for lowering the surface energy and the WPU is for enhancing the mechanical durability.
The fabrics coated with PTFE DISP/HM SiO2/FAS-17/WPU exhibited liquid repellency as signified by high static contact angles (≧97.3∘) against five pure liquids (water, ethylene glycol, sunflower oil, hexadecane, pentadecane) with surface tension values ranging from 72.8 to 27.1 mN/m. The coated fabrics also show chemical stability, mechanical stability and self-healing, which may find its application in protection garments. Moreover, the fabrics coated with PTFE DISP/FAS-17 are superhydrophobic/olephilic, which can be applied to oil/water separation based on differences in wettability of oil and water.
