摘　　要：双疏表面因在自清洁、防污、防腐蚀等方面的应用价值而受到广泛关注。然而,双疏表面在使用过程中因机械摩擦等作用,易造成微-纳结构及双疏官能团的破坏而影响双疏性能。因此,如何提高机械稳定性能已成为双疏表面在实际应用中的关键问题。首先,介绍了基材微结构对双疏表面的影响;接着,从化学刻蚀、电化学刻蚀、激光加工、电化学沉积、压印或模板等制备方法综述了微结构基材-机械稳定双疏表面的构建;指出特殊形貌基材通过尺度较大的规整凹凸结构为附着的尺度较小的纳米粗糙表面和疏液基团提供了保护,进而实现机械稳定性;最后,总结了该领域研究存在的问题,展望了未来的发展方向。Amphiphobic surface has attracted wide attention due to its application in self-cleaning,antifouling and anticorrosion.However,the micro-nanostructure and amphiphobic functional groups of the surface will be destroyed because of mechanical friction and other effects,which will affect the amphiphobicity of the surface.Therefore,how to improve the mechanical stability has become a key problem in the practical application of amphiphobic surface.Firstly,the effect of the substrate microstructure on the amphiphobic surface is introduced.Then,the construction of the microstructural substrate-mechanically stabilized amphiphobic surface is reviewed from the preparation methods including chemical etching,electrochemical etching,laser processing,electrochemical deposition,imprint or template.It is pointed out that the substrate with special morphology provides protection for the nano-sized rough surface and hydrophobic group attached by the large scale regular concave-convex structure,and thus achieves mechanical stability.Finally,the existing problems in this field are summarized,and the future development direction is prospected.
