Abstract: A method for preparing a SiO2-polyethersulfone conductive ultrafiltration membrane and the ultrafiltration membrane comprises hydrophilic CF cloth as the conductive membrane base, which provides an effective carrier for the preparation of a stable and efficient conductive membrane. After pretreatment, the silica solution was combined with the membrane via film scraping. Then phase catalysis and polymerization of PES onto the film obtained the final silica dioxide-polyethersulfone conductive ultrafiltration membrane. The silica solution was applied in the form of a coating on the hydrophilic CF cloth, in which silicon dioxide combined with the hydrophilic CF cloth, avoiding electrochemical interference. The modified hydrophilic CF cloth improved the hydrophilicity of the conductive film, with silica firmly attaching to PES and improving the stability of the SiO2-polyethersulfone conductive ultrafiltration membrane. After 8 cycles of reuse, the performance of the membrane remained stable.
