Superhydrophobic coatings enable liquids (such as water or oil) to form high contact angles and rapidly roll off their surface.Compared with traditional organic solvent-based superhydrophobic coatings,waterborne superhydrophobic coatings have become a research hotspot in recent years because of their environmental friendliness,safety and sustainability.The preparation methods of waterborne superhydrophobic coatings were introduced.To address the problems of the poor dispersibility of low-surface-energy substances in water and the limited mechanical durability of these coatings,solutions were proposed.The technical challenges encountered in the application of waterborne superhydrophobic coatings were expounded in relation to self-cleaning,anti-corrosion,and anti-icing applications.Finally,the future development directions of waterborne superhydrophobic coatings were prospected.
