Research on the preparation and property of superhydrophobic surface with micro-nano ripple structure

Superhydrophobic surfaces are widely used in various fields because of their excellent properties and are currently an important research hotspot. Here, we developed a simple method and successfully prepared a functional surface with superhydrophobic properties. The relationship between laser process parameters on the surface morphology and wettability properties of stainless steel mesh was systematically investigated, and the surface corrosion resistance, mechanical stability, and self-cleaning properties of superhydrophobic stainless steel mesh were explored. The results show that under laser ablation with optimal process parameters, the surface of the superhydrophobic SSM has a large number of laser-induced periodic micro-nano corrugated structures, which store a large amount of air in the structure to form a layer of air cushion, reducing the contact between the surface and the corrosion solution, improving the corrosion resistance of the SSM, and also showing excellent performance characteristics in terms of mechanical stability, time-sensitive, and self-cleaning performance.
