    Research on the Preparation of Modified TiO<sub>2</sub> Composite Coatings with Anti-Fouling and Flashover Resistance by ZHANG Jie, ZOU Junwen, LIU Xueguang, LI Xiaoying

    Published 2024-12-01
    “…In order to effectively reduce the occurrence of pollution flashover accidents caused by surface contamination of transmission line insulators, a new fluorocarbon coating material was prepared by combining modified nano-TiO2, PTFE and fluorocarbon resin FEVE using compressed air spraying technology.The optimum addition amount of modified TiO2&#x00A0;particles was discussed.The microstructure was studied using scanning electron microscopy (SEM) and atomic force microscopy (AFM).The hydrophobicity, self-cleaning properties and anti-ultraviolet aging resistance were analyzed using a contact angle measurement instrument.The results showed that the optimum addition amount of modified nano-TiO2&#x00A0;was 4%,the adhesion of the coating reached grade 0,and the maximum static contact angle was 121&#x00B0;.The surface of the anti-pollution flashover composite coating prepared with modified TiO2&#x00A0;exhibited numerous micro-nano scale columnar cone tip structures, resulting in higher roughness.Its hydrophobicity, self-cleaning ability, and anti-ultraviolet aging resistance were improved, demonstrating excellent antipollution flashover performance.…”
