Abstract The icing of wind turbine blades seriously affects the safe and economic operation of wind turbines, and high-quality super-hydrophobic anti-icing coatings are the current research focus. In this paper, the epoxy resin (EP) and curing agent are fluorinated modified by the compound fluorination modification method, and the surface structure of the coating is modified by ZnO nanoparticles to prepare the EP-ZnO nanocomposite superhydrophobic coating.The hydrophobicity, wear resistance and impact resistance of the coating are studied.The research results show that the composite fluorinated modification properties effectively improve the hydrophobic properties of the coating, with a contact angle of 150° and a rolling angle of 6°; the contact angle of the coating after the modification of the coating surface structure by ZnO nanoparticles reaches 158°, and the roll angle is 3°. The coating has good adhesion, stable impact resistance and wear resistance. After the wear test, the coating can still maintain high hydrophobic properties.

Key words： fluorination modification superhydrophobic coating ZnO low surface energy micro-nanostructure
