Alumina nanowire forests via unconventional anodization and super-repellency plus low adhesion to diverse liquids

Weici Wu, Xiaolong Wang, Daoai Wang, Miao Chen, Feng Zhou, Weimin Liu and Qunji Xue

Multiple facet supported alumina nanowires are produced very efficiently in a very short time via high field anodization; upon modification with perfluorosilane, the surface becomes super-repellent towards a broad range of liquids, which includes (salted) water, water emulsion, common organic liquids like glycerol and alkanes, and a variety of lubrication oils including ionic liquids, poly(-olefin), polydimethylsiloxane oils etc.
