Super-hydrophobic surface (coating) plays an irreplaceable role in the application fields of drag reduction, energy saving, anti-ice and anti-biological deposition. Recently, many bottom-up or top-down preparation strategies have been developed to build functional superhydrophobic coatings with low surface energy and rough surface structure. However, the complexity of the surface construction process of the micro-nano structure and the wearability of the micro-nano rough structure greatly restrict the preparation cost and service life of the superhydrophobic coating. It is an important development direction in this field to develop simple strategies to realize functional coatings with high wear resistance or easily repaired and renewable superhydrophobic surfaces.
