A simple and effective method of manufacturing slippery liquid-infused porous surface (SLIPS) on stainless steel through femtosecond Bessel laser beam direct inducing has been developed. The ice restraint properties of SLIPS, including icing delay and ice-adhesion strength, are significantly improved. SLIPS exhibits great durability and can be produced on different metal substrates with excellent liquid resistance and anti-icing property, expanding its application in the field of ice resistance.
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.
