摘要：
Designing micro-nano structure is one of promising method to fabricate hydrophobic surfaces. In this paper, we demonstrated a combining etching and heat treatment approach to achieve a superhydrophobic surface on brass. Following by simple modification using stearic acid, the water contact angle on micro-nano structured brass was 153.6 degrees, along which exhibited good and persistent corrosion resistance in 3.5 wt% NaCl aqueous solutions. This method could provide an effective route to fabricate superhydrophobic surface with corrosion resistance and self-cleaning properties for applications in the metal alloys materials.
