    Superhydrophobic surfaces with a high contact angle and a low sliding angle are promising candidates for corrosion resistance. In general, an excellent chemical and mechanical stability is the most critical property for superhydrophobic surfaces. In this paper, we proposed a facile, effective and environment friendly method using a simple solution immersion method to fabricate a superhydrophobic surface on copper mesh. The as-fabricated superhydrophobic surface possessing dendritic rough structure and low surface energy displayed a high contact angle of 155.5°. The excellent anti-fouling and self-cleaning properties were demonstrated. The mechanical stability was also exhibited when it was subjected to an impact by a continuous stream of water. In addition, the excellent chemical stability both in acidic and alkaline solutions and the outstanding anti-corrosion effect were showed in electrochemical test due to the air pockets formed between the superhydrophobic surface and water which can well block corrosive medium. This method is facile, timing-saving and environment friendly, which can play a crucial role in practical industries application of superhydrophobic surface.
