摘　　要：浸润性可逆调控响应型表面是一种通过外部刺激响应材料或形貌可控微观结构实现静态/动态浸润性可逆转换的固体表面,可有效解决传统特殊浸润表面性能单一、结构固定等问题,更符合基础研究和工程现场的多样化、时变性应用需求。着眼于表面浸润性能主观调控中关键技术的发展态势,综述分析了响应型固体表面的类型特征、制备方法和应用前景。根据外部刺激类型,将响应型功能表面归纳为基于化学组成和基于微观结构两大类,重点围绕光响应型、温度响应型、pH响应型和磁场响应型等功能表面的响应材料、响应原理、调控机制及性能特点展开系统分析,聚焦于两类响应功能表面制备方法,梳理其基本原理、技术特色及其优劣性,并深入探讨了两类表面在可控油水分离、微液滴/流体操控等领域的潜在应用价值。最后指出了浸润性可逆调控表面在发展过程中需要面临的挑战和仍需注重解决的问题,希望能为后续人工响应型功能表面研究工作的大规模推进提供参考。Responsive surfaces with reversibly switchable wettability are a kind of solid surfaces that can realize reversible conversion of static wettability or dynamic wettability through stimulus-responsive materials and/or shape-controlled microstructures.It can effectively solve the problems of traditional special wetting surfaces with single performance and fixed structure,and better meet the complex needs of basic research and engineering applications.This study focuses on development of key technologies in the subjective regulation of surface wetting properties,and reviews the characteristics,fabrication methods and application prospects of the responsive surfaces.The responsive surfaces are classified as based on surface chemical composition and microstructure according to the type of stimulation.The systematic analyses of light,temperature,pH and magnetic responsive surfaces and so forth are carried out that concentrate on the common materials,response principles,research status and characteristics.Furthermore,the basic principles,technical features and advantages/disadvantages of preparation methods are summarized based on two kinds of responsive surfaces.The potential applications with current problems in the fields of controllable oil/water separation,microdroplet/fluid manipulation,sensors and so on are also illustrated.Finally,the challenges and trends in the future development of the responsive surfaces are summarized,hoping for providing a reference for the subsequent large-scale advancement of research work on artificially responsive functional surfaces.
