Improved Antifouling Property of PVDF Membranes with Crosslinked PEG

In order to increase antifouling ability of PVDF membrane, crosslinking PEG as antifouling medium in membrane bulk was studied. PEG with different moleculer weight were crosslinked in membrane solution with TMC as crosslinking agent, ATR demonstrated crosslinked PEG were retained in membrane bulk and surface wetting property was improved with contact angle characterization. According to the dynamic fouling test of BSA solution, the PVDF-T1000 membrane exhibited the best antifouling ability with the FRR value as high as 90%.
