Slippery Liquid-Infused Porous Surface on Metal Material with Excellent Ice Resistance Fabricated by Femtosecond Bessel Laser

Slippery liquid-infused porous surface (SLIPS) has shown great application prospects because of the great liquid repellency and ice resistance. However, there are a few types of research on different metal material to fabricate SLIPS. Here, a simple and effective method is developed on a stainless steel surface to manufacture microporous structure by femtosecond Bessel laser beam direct induce. By fluoroalkylsilane modification and infusing lubricant, SLIPS is successfully obtained. The ice restraint properties of the SLIPS are studied, including the characterization of icing delay and ice-adhesion strength, which significantly increase the icing-delay time and reduce the ice-adhesion strength. Moreover, SLIPS exhibits great durability after hydraulic pressure, salt fog, high-, and low-temperature cycle. Based on this method, SLIPS can be produced on different metal substrates including Al, Zn, Ti, Cu with excellent liquid resistance and anti-icing property, which greatly expand the application of SLIPS in the field of ice resistance.
