摘要
具有非润湿和自清洁特性的超疏水表面由于其广阔的应用前景而引起人们的极大关注。介绍超疏水状态下Wenzel和Cassie-Baxter 2种接触模型及其相互关系,讨论2种模型下表面微细结构对接触角的影响。从构造表面微细结构和低表面能物质修饰2个方面总结近年来超疏水表面制备技术的研究进展,并对超疏水表面的研究进行展望。
Superhydrophobic surface with non-wetting and self-cleaning properties have aroused great interest owing to their potential application.Two models under superhydrophobic state,Wenzel model and Cassie-Baxter model,and their relationship were introduced,and the influence of surface rough microstructure on contact angle was discussed.Superhydrophobic surface preparation technology by surface rough microstructure preparation and low surface energy material modification was summarized,and the development of superhydrophobic surface was prospected.
