Bio-inspired surfaces with special wettability include superhydrophilic surfaces and various kinds of superhydrophobic surfaces. Since these surfaces possess the properties as self-cleaning, anti-icing, anti-drag, and so on, they have attracted tremendous attentions of international academia in recent years. With the rapid development of ultrafast lasers, various surfaces with special wettability can be fabricated by means of the ultrafast laser. Compared to other methods, the ultrafast laser surface treatment technology is simple, flexible and controllable. The research progress in combination with the research achievements in our group in this field is reviewed.
