摘要
润湿性是固体表面的重要特征之一。人工控制和制备固体表面润湿性已成为研究的热点，而且逐渐被应用于国防、工农业生产和人们日常生活等不同领域。论述了固体表面润湿性的有关理论基础，包括表面张力、表面自由能、润湿过程及其条件。分析了固体表面接触角的Young模型、Wenzel模型和Cassie模型等几种理论模型，以及解释了接触角滞后现象。
The wettability is one of the characteristic properties of solid surfaces. It has been noticed that the fabrication and control to the wettability of solid surfaces, which was widely used in many fields. Some basic theories were discussed in the paper, such as surface tension, surface free energy, wetting courses and conditions. Three models of contact angle on solid surfaces were analyzed, including Young model, Wenzel model and Cassie model. Besides, the lag action of contact angle was explained.
