Cu2O coated meshes with coral reef-like micro/nanostructures have been successfully fabricated via a facile spray-and-dry method, without using low surface energy materials. The obtained Cu2O coated superhydrophobic surface, which is similar to the lotus leaf structure, had a contact angle of 159.6 degrees and a sliding angle of 1 degrees. Based on the design of a miniature apparatus, the superhydrophobic mesh can separate different kinds of oils regardless of the light oil or heavy oil in the mixture with excellent separation efficiency. It is expected that this convenient technique may open a novel approach in future development of superhydrophobic coating technology. (c) 2017 Elsevier B.V. All rights reserved.
