Facile fabrication of robust and photo-thermal super-hydrophobic coating with efficient ice removal and long-term corrosion protection

Multifunctional integration is an essential feature to broad the practical application of artificial super-hydrophobic coating in numerous fields. Herein, a passive anti-icing and active photo-thermal deicing super-hydrophobic coating with excellent mechanochemical durability, self-healing and long-term corrosion protection performances has been developed by a facile and environmentally friendly heterogeneous hybrids approach. The prepared coating exhibits excellent super-hydrophobicity with CAs up to 161.9°, SAs is only 4.2° and the adhesive force value of microdroplets is ∼16.8 ± 0.6 μN. The composite coating holds its prominent water repellency even after various extreme treatments, including high-low temperature alternation, 60 m sandpaper abrasion, kneading stability and corrosive medium immersion. Moreover, the coating also presents remarkable self-cleaning properties both in air or oil even after mechanical abrasion and significantly healable capabilities against O 2 plasma etching . Furthermore, the influence mechanism of the heterogeneous hybridization on thermal property and corrosion resistance of the coating were systematically analyzed. In addition, utilizing the superior water repellence and the photo-thermal performance, the coating could efficiently delay the freezing time and active deicing after 808 nm NIR laser irradiate. Therefore, the multifunctional integrated super-hydrophobic coating will be promising for several industrial fields.
