摘要：Metal corrosion causes tremendous financial loss and disasters every year. Inspired by "lotus effect," a superhydrophobic stainless steel surface with anti-corrosion property was realized in this study. The bioinspired micro-nano structures were fabricated by utilizing two chemical etching procedures. The water contact angle (CA) of the prepared surface reached 173 degrees. The correlative mechanism between CA and surface morphology was elucidated by adjusting the key reaction conditions. Electrochemical corrosion test showed that the bioinspired superhydrophobic stainless steel possessed a polarization resistance that is 28.9 times higher than that of common stainless-steel surface.
