Wettability is one of the most important properties which weigh hydrophobic capability of superhy-drophobic surface and it depends on both the chemical composition with low surface energy and the surface microcos-mic structure. In this paper the wettability theory, Wenzel model and Cassie model are briefly reviewed. The latest re-search progresses of superhydrophobic surface are summarized, including manufacturing, application and theoretics. The application in self-cleaning and drag reduction is detailedly introduced. Finally questions of superhydrophobic sur-face research are brought forward and the prospect of the development in many field is proposed.%润湿性是衡量超疏水表面疏水强弱的最重要特征之一,主要由表面化学组成和表面微观结构共同决定.简述了超疏水表面的润湿性理论,综述了超疏水表面的最新研究进展,包括制备方法、应用研究及理论分析,详细介绍了其在自清洁和减阻方面的应用,最后提出了现阶段超疏水表面研究所面临的问题,并展望了其诸多领域的发展前景.
