摘要：

In this study, a multifunctional superhydrophobic coating was developed with the aim of addressing the needs of industrial metallic materials for self-cleaning, anti-icing, and anti-corrosion applications. Titanium dioxide (TiO2) particles were loaded onto the surface of zirconium oxide (ZrO2) particles using the sol-gel method and were surface modified with hexamethyldisilazane (HMDS) to produce modified ZrO2-TiO2 composite particles. The composite particles were mixed with polydimethylsiloxane (PDMS) and epoxy resin (EP) and applied to the brass substrate using a spraying technique to form a robust superhydrophobic coating. The coating exhibited a water contact angle (WCA) of up to 160.5 degrees and a water slide angle (WSA) as low as 6.3 degrees. This paper thoroughly investigated and characterized the coating, and its excellent self-cleaning properties and abrasion resistance were tested. Anti-icing tests at low temperatures demonstrated that the coating significantly delayed the icing time on brass surfaces. Additionally, the coating showed a significant reduction in the corrosion rate compared to untreated brass. In summary, the coating fulfills the requirements of practical applications considerably.
