超疏水表面的研究进展

Progress in Superhydrophobic Surfaces

表面的浸润性是决定材料应用的一个重要性质,许多物理化学过程,如吸附、润滑、黏合、分散和摩擦等均与表面的浸润性密切相关。近年来,由于超疏水表面在自清洁表面、微流体系统和生物相容性等方面的潜在应用,有关超疏水表面的研究引起了极大的关注。本文综述了超疏水表面研究的新进展:简单介绍了表面浸润性的表征手段和影响因素,归纳了超疏水表面的制备方法和相关的理论分析,对超疏水表面研究的发展进行了展望。

Surface wetting behavior is of great importance in determining the application of various materials. Many physicochemical processes, such as adsorption, lubrication, adhesion, dispersion, friction and so forth are closely related with the wettability of materials. In the last decade, surfaces with ultra hydrophobicity have aroused much research interests owing to their potential application in self-cleaning coatings, microfluidics and biocompatible materials and so on. The recent progress in the study of superhydrophobic surface is summarized in three parts. In the first part the characterization and influences of wettability are briefly introduced; in the second part new development of superhydrophobic surfaces is summarized from both experimental and theoretical aspects; in the third part the prospect of the development in this field is proposed.
