Photo-Responsive Superwetting Surface
Photo-responsive surfaces, especially for the photo-responsive superwetting surface, have aroused great interests in smart control devices for a few years due to their remote control and selectivity. This chapter focuses on the photo-responsive wettability on the superwetting surface and their typical applications, particularly on switchable wettability on photo-responsive surfaces and their applications such as droplet actuation, adhesion control, liquid printing and oil-water separation. Finally, our personal point of the prospects and challenges of the photo-responsive wettability surfaces are presented.
