摘　　要：界面浸润性是材料科学的根本问题之一,浸润性调控的研究无论在探索新知识,还是创造新应用方面都有重要意义.在过去20余年里,江雷团队通过向自然学习,总结了超浸润现象的3条基本原理:(1)静态浸润性决定于纳米结构和表面能的协同效应;(2)表面超亲超疏在纳米结构上的转变点为液体亲疏界限;(3)化学组成梯度、粗糙梯度、曲率梯度等调控流体输运的方向.基于这些原理,进一步将超浸润界面材料体系扩展到界面化学.江雷团队建立了包括64个组合方案的超浸润界面材料体系,并拓展到不同压力和温度范围的各种液体体系,引领并推动了该领域在全球的发展.本文介绍了超浸润界面的设计与液/气/固三相界面浸润的新规律,若干超浸润界面材料体系在环境、农业、健康、材料、能源等领域的应用,以及近期关于量子限域超流领域的研究和应用前景.Interfacial wettability is one of the fundamental problems in material science.The research on wettability regulation is of great significance in exploring new knowledge and creating new applications.Learning from nature,Prof.Jiang has summarized three basic principles of superwettability:(1)The static wetting is determined by the cooperative effect of nanostructure and surface energy;(2)the transition point of the superlyophilicity and superlyophobicity on the nanostructure is the lyophilicity-lyophobicity limitation;(3)the direction of liquid transport is regulated by chemical composition gradient,rough gradient,curvature gradient,etc.Based on these principles,he further extended the superwettability interfacial material systems to interfacial chemistry.He established a superwetting interfacial material system including 64 combinations,and expanded to various liquid systems with different pressure and temperature ranges,leading and promoting the global development of this field.In this paper,we will introduce the design of superwetting interface and the new law of liquid/gas/solid three-phase interfacial wettability.Based upon the new law of three-phase interfacial wettability,we state the application of water-oil separation,pesticide spraying,electrochemical sensors,and photoelectric material patterning.And the recent research and application prospect in the field of quantum-confined superfluid are discussed.In the part of water-oil separation,focusing on the key issue of constructing membrane materials with both fine pore structure and super-wetting properties,without changing the traditional separation membrane preparation process,the micro-nano multi-level structure of the membrane surface is constructed through structure-induced tuning,and the surface is chemically modified.Synergistic action is used to realize the regulation of membrane transport behavior of water droplets or oil droplets,and a series of novel structural membrane separation materials have been successfully prepared,realizing high-precisio
