Abstract

A modified composite ultrafiltration membrane was prepared using polyethersulfone as a polymer, polyvinylpyrrolidone as a pore-forming agent, N-N dimethylacetamide as a solvent, silver phosphate and polyhexamethylene biguanidine hydrochloride as antimicrobial agents. The morphology, hydrophilicity and water flux of the membrane materials were investigated by scanning electron microscopy, surface contact angle determination and antibacterial test. Their anti-fouling and antibacterial effects were investigated. The results showed that when the mass of silver phosphate was 0.5% of solvent mass and polyvinylpyrrolidone was 0.5% of solvent mass, the contact angle of the modified ultrafiltration membrane was 68.2° and the hydrophilicity was obviously improved and the antibacterial property was 90.54%.
