A Brief Review on Bioinspired ZnO Superhydrophobic Surfaces: Theory, Synthesis, and Applications

Due to the intensive demand in the development of superhydrophobic surfaces both in theory and application, superhydrophobic research on ZnO materials has exponentially grown over the last several years. One of the main advantages of the ZnO materials is the relative easiness to produce various surface morphologies, which is quite meaningful to study the influence of morphology on wetting property. The synthesis approaches of ZnO materials include thermal oxidization, hydrothermal method, chemical etching, spray coating technique, electrochemical method, and others. This review is a representation of the recent achievement on ZnO superhydrophobic surfaces.
