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 SiO nanoparticles are used to create high surface roughness. The prepared surfaces exhibit excellent superhydrophobicity and high oleophobicity once the nanoparticles are treated with 1 H,1 H,2 H,2 H-perfluorodecyltriethoxydsilane (FAS-17). Water and ethylene glycol contact angles of the coatings can reach up to 172 ? 2? and 157 ? 2?, respectively. After undergoing strong adhesive tape peeling and mechanical abrasion, the coatings still maintain good amphiphobicity.
具有超疏水和超疏油特性的功能表面在许多应用中备受关注。然而，这类表面通常难以获得。尽管最近已开发出一些超双疏表面，但制备具有良好耐久性的此类表面仍然面临挑战，而耐久性是实际应用中的关键问题。在本研究中，我们展示了一种使用两种纳米颗粒制备耐用超疏水和高疏油表面的简便方法。环氧树脂用作粘合材料以提高表面的耐磨性。氧化锌纳米颗粒和二氧化硅纳米颗粒用于产生高表面粗糙度。一旦用1H,1H,2H,2H - 全氟癸基三乙氧基硅烷（FAS - 17）处理纳米颗粒，所制备的表面就会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°。经过强力胶带剥离和机械磨损后，涂层仍保持良好的双疏性。
