摘　　要：由于超疏水表面在防腐、油水分离、流体减阻和液体转移方面的应用潜力,如何制作性能优异的超疏水表面成为研究热点。材料表面的形貌特征是决定其润湿性能的一个重要因素,因此,通常采用表面结构化来获得超疏水性能。在材料表面构织微纳结构方面,基于脉冲激光的微纳加工技术具有得天独厚的优势,尤其是在制作特定图案的复杂结构方面。本文根据激光器的脉冲宽度分类,通过刻蚀后材料表面形貌和润湿性特征对激光制作超疏水表面的基本理论和典型工艺方法进行介绍和总结,并对超疏水表面的发展前景作出展望。Over the past few decades, many methods have been developed to fabricate superhydrophobic surfaces because these surfaces are useful in several important applications such as anti-corrosion, oil-water separation, friction reduction, and liquid transportation. Surface morphology is a key factor to determine the wettability of a solid surface, and patterning is one of the effective ways to change the surface morphology and to improve the wetting properties. Laser patterning using a pulse laser source is a unique technique that can modify the surface morphology with very limited distortion of the bulk material. Moreover, it is a noncontact method, and complex patterns can be created. In this paper, we summarized several typical approaches, theories and relevant applications of laser fabricated superhydrophobic surfaces.
