摘要:In this work, we present a novel etching method to fabricate the superhydrophobic Al surfaces in a salt solution. Hierarchical rough structures composed of micrometer-scale pits, protrusions, and rectangle plateaus and nanometer-scale step-like structures are formed on the Al surfaces by the self-assembled primary cell assisted etching and the preferential corrosion of grain boundaries and dislocations. After fluoroalkylsilane modification, the superhydrophobic Al surfaces with a 166.4 degrees water contact angle and a 1 degrees rolling angle are obtained. The developed method does not use any strong acids and has a smaller harm to the environment and operators.
