Abstract

Abstract: An ultraviolet (UV)-durable super-hydrophobic ZnO/Ni lotus-like nanostructure was fabricated via a simple two-step electrodeposition method at low temperature. The as-prepared ZnO/Ni nanostructure showed excellent UV-durable super-hydrophobicity and water ultra repellency. The Ni nanoclusters with different density could be successfully fabricated on the surface of ZnO NR by modulating the electrodeposition time of Ni nanoclusters, which affected surface roughness and wettability. The triple-level roughness resulted from high density Ni nanoclusters played a important role in the super-hydrophobicity of ZnO/Ni nanostructure. This super-hydrophobic surface showed high stability in water for long term. Furthermore, the layer of Ni nanoclusters avoided the photoinduced wettability conversion of ZnO and hence greatly improved the UV-durability of this super-hydrophobic surface, which were essential elements for practical applications. This simple method could be applied to various substrates, such as metal surfaces and other electric conductive substrates.
