透明超疏水涂层不仅具有优异的超疏水特性，而且具有很好的透光性，在汽车、飞机等挡风玻璃、太阳能挡板、建筑物玻璃等方面有广泛的应用前景，但是目前制备得到的透明超疏水涂层普遍存在耐磨性差和被油污染后失去超疏水性能的缺点。

  “目前制备透明超疏水表面的一个重要方法是采用涂料涂覆，但是纳米颗粒与基体之间结合力弱导致涂层极易被破坏”课题组组长范孝良教授解释道，“由于油的表面张力小于水，故当油渗入涂层中后极易导致涂层失去超疏水性”

  为了实现涂层的透明性，需要使材料的反射率接近空气（nair=1），二氧化硅（n=1.43）和硅橡胶（n=1.40）是两种极具潜力的透明涂层材料；含氟聚合物因其具有良好的低表面能而被广泛用作自清洁材料。相关论文第一作者王鹏讲师与其它研究人员通过巧妙的设计，将表面接枝有含氟低表面能官能团的二氧化硅纳米颗粒部分嵌入到硅橡胶基体中，同时实现了耐油污性和耐磨性。

  相关成果发表在（Journal of Materials Chemistry A, 2016,DOI: 10.1039/c6ta01082b）及1项发明专利申请（CN105176150A）。在此基础上，该课题组将进一步探索此型结构材料在电力系统中的应用。

  This paper reports an easy method to prepare a transparent superhydrophobic coating which shows a robust resistance to oil contamination, knife-scratch, sandpaper abrasion and strong acid/base attack. A PDMS interlayer was introduced to support the partially embedded fluoroalkylsilane treated silica nanoparticles, and thus the coating retained superhydrophobicity and self-cleaning properties after knife-scratch or 9 sandpaper abrasion cycles. An OSP scraping ink bar was introduced to control the thickness of the silica nanoparticle suspension, and thus the coating shows good transparency for visible light. Moreover, this transparent superhydrophobic coating shows self-cleaning properties in either air or oil environment.
