The solid surface icing issue has significant impacts on both industrial sectors and human life, hence exploring novel anti-icing materials is of great importance. In this study, PDMS with low surface energy was sprayed onto aluminum plates as a binder. Fe3O4 and Fe3O4/SiO2 dispersion liquids were separately sprayed to form photothermal hydrophobic coatings. Fe3O4 provides photothermal effects and has a certain rough structure. When SiO2 is added, the hydrophobicity is further enhanced, with a water contact angle reaching 155°. This coating greatly delays the icing time and accelerates frost melting. Under sunlight, the temperature rise can reach 71.8℃. The self-cleaning ability of this coating ensures it is not heavily polluted and possesses certain resistance to wind and sand impact, demonstrating good mechanical stability.
