Abstract: Anti-icing has now become an urgent problem to be solved in the fields of aircraft structure, power transmission lines, and refrigeration equipment. This paper conducted a comprehensive comparative study on the anti-icing characteristics of three independently developed hydrophobic/superhydrophobic composite coatings, focusing on the analysis of the advantages of each coating in mechanical durability and deicing under ultra-low temperature conditions. The results show that the primer-finish composite superhydrophobic coating has excellent mechanical durability, and the ice adhesion strength is less than 30 kPa after 40 abrasion under a 250 g load of the abrasion meter and after 100 freezing/melting cycles; the hydrophobic nanoparticle-lubricating grease composite coating has excellent deicing performance at ultra-low temperature −150℃, and its initial ice adhesion strength is only 11.5 kPa. The research results of this thesis will provide useful theoretical and practical guidance for the application of hydrophobic/superhydrophobic coatings in the field of anti-icing.
