Preparation and Application of Superhydrophobic Surface Materials

Abstract

Superhydrophobic materials have attracted wide attention due to their special wettability on the surface. In this paper, the basic definition, principle, and several common wetting models of superhydrophobic are summarized firstly. Then, the advantages and disadvantages of commonly used methods for preparing superhydrophobic materials are briefly analyzed, including dip coating method, spraying method, template method, chemical vapor deposition method, etching method, electrospinning method, phase separation method, and layer-by-layer assembly method. Finally, the application of superhydrophobic materials in oil-water separation, moisture-proof packaging, self-cleaning, and other fields is summarized and elaborated. The application of smart superhydrophobic materials which can respond to external stimuli such as pH, light, and temperature is also introduced. The purpose is to provide reference for the development of superhydrophobic materials. Preparing excellent superhydrophobic materials in a simple and environmentally friendly way is the key to meet the requirements of current industrial production.
