Abstract: The inorganic porous membrane material was prepared by a sol-gel method on glass substrates and porcelain insulators respectively .The surface of samples were tested by hydrophobic and dust-proof, and some samples were conducted an electrical performance test and a comparison of artificial simulated sediment test , and the microstructure was analyzed by SEM and AFM .The results show that , the inorganic porous membrane material after high temperature hardening has the antifouling performance and a good anti-aging and anti-flashover performance due to its special structural features , and self-cleaning effect is remarkable .
