Abstract: Low surface energy coating is a rapidly developed coating system in recent years. Coatings prepared by low surface energy coating have hydrophobic properties. Its research in superhydrophobic, anti-icing, self-cleaning, anti-fouling,anti-drag and noise reduction, anti-corrosion and other fields is gradually deepening and has a very wide application prospect.The theoretical model and principle of low surface energy coating were briefly introduced, and the different application fields of low surface energy coating were classified. Meanwhile, the latest research achievements in related field were summarized.Finally, the problems that need to be solved for low surface energy coating were proposed, and the future development direction of the coating was prospected.
