Simultaneous Fabrication of Superhydrophobic Coatings on Cathodic and Anodic Copper Surfaces with Micro/Nano-Structures

In this letter, we presented a novel one-step electrodeposition method to prepare two superhydrophobic coatings, and it can simultaneously fabricate two different superhydrophobic coatings on cathodic and anodic copper surfaces, respectively. The as-fabricated cathodic superhydrophobic coatings need only 15 sec, and the anodic superhydrophobic coatings need 5 min, which is shorter than that in the reported literature. The cooperation of hierarchical structures and low surface energy plays an important role in the formation of superhydrophobicity. Furthermore, both of the coatings are bulk materials, and have a good extensive application prospect. (c) 2012 The Electrochemical Society. All rights reserved.
