Fabrication of Superhydrophobic Surfaces on Metal Substrates by Nanosecond Laser

Abstract:

Superhydrophobic surfaces on aluminum, stainless steel, titanium alloy, and copper substrates were fabricated by nanosecond laser etching and fluoroalkylsilane modification. Compared with the existing laser beam machining technologies, such as femtosecond laser etching and picosecond laser etching, for fabricating superhydrophobic surface, the method developed by us is inexpensive and high efficiency. The influence of laser etching parameters on the surface morphology and wettability on the superhydrophobic surfaces were studied through orthogonal analysis method. The good superhydrophobicity with contact angle larger than 160° was achieved on the aforementioned 4 kinds of metals.
