Abstract:
A facile fabrication method is presented for a super-repellent surface, in which a silicon wafer is etched with a wet chemical method and treated by a fluorinated self-assembled monolayer. This surface is composed of harshly rough nanostructures and highly dense nanoholes. The contact angle of both water and oil with the surface is larger than 150 degrees. The self-cleaning capability of the surface allows for the removal of sticky powders with glycerin droplet. Any desired part(s) of the super-repellent surface can be turned superamphiphilic by simply exposing the desired part(s) to ultraviolet light.

The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
