摘要/Abstract

摘要： Here, superhydrophobic cuprous oxide (Cu₂O) with hierarchical micro/nanosized structures was synthesized via spray-assisted layer by layer assembling. The as-prepared superhydrophobic meshes with high contact angle (159.6°) and low sliding angle (1°) are covered with Cu₂O "coral reef" -like micro/nanosized structures. Interestingly, the superhydrophobic mesh surfaces became superhydrophilic again due to the oxidization of Cu₂O to CuO by annealing at a higher temperature (300℃). And the superhydrophobic properties would be recovered by heating at 120℃. Furthermore, the superwetting meshes were applied to design a miniature device to separate light or heavy oil from the water-oil mixtures with excellent separation efficiency. These superwetting surfaces by simultaneously spray-assisted layer by layer assembling technique show the potential application in universal oil-water separation.
