Abstract: Bionic superhydrophobic materials have been identified as innovative solutions for anti-pollution flashover applications due to their exemplary water repellency and self-cleaning properties. Inspired by the hydrophobic transfer properties of room temperature vulcanized (RTV) silicone rubber coatings, superhydrophobic coatings are successfully endowed with unique superhydrophobicity transfer property and excellent durability by embedding migrating agents containing low surface energy molecules in resin-based primers. When the surface of the superhydrophobic coating is stained by a mixture of diatomite and NaCl, the silicone oil molecules can migrate from the coating to the soiled layer and carry out surface chemical modification, and the surface wettability of the soiled layer gradually changes from hydrophilicity to hydrophobicity, and ultimately to superhydrophobicity. The analysis indicates that the migration agent and its content play a pivotal role in the superhydrophobic migration characteristics, meanwhile, the migration ability is contingent upon the migration time, the pollution level, the ambient temperature, as well as the composition and structure of the primer and other factors. The results of the artificial pollution flashover test demonstrate that the superhydrophobic migration characteristics can enhance the anti-pollution flashover performance of insulators coated with superhydrophobic coatings.
