Abstract:A new method of fabrication superhydrophobic surface by means of ECM was developed.The fabrication mechanism was based on the fact that the grain boundaries/dislocations were micro/nano-scale and more likely to be anodic dissolved than that of grain self,so the multi-scale micro/nano-structures surface can be generated by an applied electric field and the chemical solution.The relationship among processing quality,efficiency and conditions was studied in experiments herein.The results show that ECM can be used to fabricate dual-scale micro/nano-structures on aluminum surfaces,and further applied to generate the large size of superhydrophobic surface.The method is easier to control the reaction process than chemical etching meanwhile more economical than other techniques.After modified with low surface energy materials,the surface exhibits superhydrophobic property with water contact angle of 167° and tilt angle less than 3°.
