Icing always threatens the safe operation of power system. In the past few decades, researchers have taken various measures to prevent the icing on the surface of power equipments, but these measures can not fundamentally solve this problem. Due to its unique micro-nano structure and low surface energy materials, superhydrophobic coating can delay icing and reduce the adhesion ability of surface ice at low temperature. Therefore, started with the anti-icing mechanism of superhydrophobic coating, this paper focuses on the experimental research status of anti-icing of superhydrophobic coating at home and abroad, divides the factors affecting the anti-icing performance into environmental factors and substrate factors, analyzes the limitations of the current schemes, and expounds the latest design and preparation progress on improving the mechanical robustness of superhydrophobic coating. Finally, the problems existing in the application of superhydrophobic coating in power system and the future development direction are put forward. This review is helpful for researchers to establish test specifications for evaluating the antiicing performance of superhydrophobic coatings and promote their application in power system.
