主　　题：Superhydrophobicity Water contact angle Aluminum alloy Micro-nano structure 

摘      要：A simple technique was developed for the fabrication of a superhydrophobic surface on the aluminum alloy sheets. Different hierarchical structures（Ag, Co, Ni and Zn） were formed on the aluminum surface by the galvanic replacement reactions. After the chemical modification of them with fluorination, the wettability of the surfaces was changed from superhydrophilicity to superhydrophobicity. Scanning electron microscopy（SEM）, energy dispersive spectrometry（EDS） and water contact angle measurement were performed to characterize the morphologi- cal characteristic, chemical composition and superhydrophobicity of the surfaces. The as-prepared superhydrophobic surfaces showed a water contact angle as high as ca.160° and sliding angle as low as ca.3°. We hope the method to produce superhydrophobic surface can be used in many fields.
