Abstract: Superamphiphobic surface with water and oil repellent properties guides the design of surface under oil and/or water environment. In this review,we focus on the fabrication and application of superamphiphobic surface. Primarily,we highlight the bottom-up methods like sol-gel method,self-assembly and phase separation,and the top-down methods like etching process and nanoimprint lithography technology for the fabrication of superamphiphobic surface. The top-down methods are more efficient to fabricate an overhang structure which makes the superamphiphobic property stable,while the processes tend to be complex. Next,we propose hat these unique surfaces are promising in self-cleaning,anti-adhesion,anti-corrosion and drag reduction under oil and/or water environment and the application to microfluidic device should be further explored. Additionally,long durability of superamphiphobic surface in practical application is important. Finally,we prospect that research emphasis of superamphiphobic surface is to prepare superamphiphobic surface with enhanced durability to fulfill practical applications by an easier method.

摘要： 超双疏表面拒水又拒油的特性指导着油水共存环境下材料表面的设计。本文概述了其构筑方法包括溶胶-凝胶法、自组装法、相分离法等自下而上的方法,以及刻蚀法、纳米压印法等自上而下的方法,并指出后者相比前者更易于构筑有利于形成超双疏表面的倒悬结构,但往往存在制备过程繁琐的问题。此外,文中简述了超双疏特性主要用于构建油污环境下的自清洁表面,提高表面抗黏附能力,实现油水环境下的减阻作用等,并提出可进一步探索该特性在微流控管道设计领域的应用。最后展望了该领域未来的研究重点是探索简易的制备方法来构筑超双疏表面,在确保良好超双疏特性的前提下提高其耐久性,以满足在实际环境中的应用。
