One-step fabrication of an anti-corrosion superhydrophobic surface on stainless steel

A one-step laser-processing method is employed on a common laser making machine to develop superhydrophobic surfaces on stainless steel. Without any surface modification, the laser-textured substrates obtained superhydrophobicity after kept in sealing bags for 12 days. The average contact angle value of the as-prepared samples is above 150 degrees. The superhydrophoic surfaces possess good self-cleaning and anti-corrosion properties. The facile, cost-effective and eco-friendly method will have great potential in the mass-production of superhydrophobic surfaces.
