Abstract

Due to its extreme non-wetting properties, superhydrophobic surface has a wide range of potential applications in the fields of drag reduction, wear resistance, anti-corrosion, anti-icing, self-cleaning, etc. Surface roughness and low surface free energy are the two determinants of forming superhydrophobic surface and the main reasons of excellent tribological properties of superhydrophobic surface. In this paper, the research on superhydrophobic surface in the field of tribology in recent years is summarized. Firstly, the related theories of the tribology of superhydrophobic surface are analyzed. Then the research status of superhydrophobic surface in the field of tribology is emphatically expounded, and the factors affecting the tribological properties of superhydrophobic surface and its mechanism are discussed. In addition, the tribological study of wear-resistant superhydrophobic surface and slippery liquid infused porous surface(SLIPS) are also analyzed. Finally, the paper puts forward the focus and direction of tribology research on superhydrophobic surface. This review, which has important theoretical and practical significance for expanding the application field of superhydrophobic surface, aims to attract more scholars’ attention to the tribological study of superhydrophobic surface.
