摘要：

A fast, facile one-step process was developed to fabricate superhydrophobic surfaces by electrode-positing copper substrate in an electrolyte containing lanthanum chloride (LaCl3 center dot 6H(2)O), myristic acid (CH3(CH2)(12)COOH) and ethanol. Morphology and the chemical structure and composition of the superhydrophobic surface were investigated with SEM, FTIR, XRD, and EDX, respectively. The results indicate that the shortest process for constructing superhydrophobic surface is 1 min, the maximum contact angle is 165 degrees and rolling angle is less than 2 degrees. In the process of electrodeposition time, structure of cathodic copper surface transforms from the blossom buds into nanostructure assemblies, flowers and then into nanorods. In addition, the method can be extended to effectively prepare a superhydrophobic surface with rare-earth element on general conductive material. (C) 2012 Elsevier B.V. All rights reserved.
