具有超疏水和超疏油性质的功能表面在许多应用中具有极大的兴趣。然而，这样的表面通常难以获得。尽管近年来已经开发出了一些超双疏表面，但制备具有良好耐久性的超双疏表面仍然是一个挑战，这是实际应用中的一个关键问题。在这项研究中，我们展示了一种简便的方法，使用两种纳米粒子制备耐用的超疏水和高度疏油表面。采用环氧树脂作为粘接材料，提高了表面的耐磨性。ZnO纳米颗粒和SiO2纳米颗粒用于产生高表面粗糙度。经1H，1H，2 H，2 H-全氟癸基三乙氧基硅烷（FAS-17）处理后，纳米粒子表面表现出优异的超疏水性和高疏油性。涂层的水和乙二醇接触角分别可达172 2和157 +/- 2度。涂层经强力胶带剥离和机械磨损后仍保持良好的两疏性。
Functional surfaces with superhydrophobic and superoleophobic properties are of great interest in many applications. However, such surfaces are generally difficult to obtain. Although a few superamphiphobic surfaces have been developed recently, a challenge still remains in preparing such a surface with good durability which is a critical issue in practical application. In this study, we demonstrate a facile method for preparing durable superhydrophobic and highly oleophobic surfaces using two kinds of nanoparticles. Epoxy resin is used as the adhesive material to improve the wear resistance of the surfaces. ZnO nanoparticles and SiO2 nanoparticles are used to create high surface roughness. The prepared surfaces exhibit excellent superhydrophobicity and high oleophobicity once the nanoparticles are treated with 1H,1H,2H,2H-perfluorodecyltriethoxydsilane (FAS-17). Water and ethylene glycol contact angles of the coatings can reach up to 172 2 and 157 +/- 2 degrees, respectively. After undergoing strong adhesive tape peeling and mechanical abrasion, the coatings still maintain good amphiphobicity.
