| Abstract: | In order to improve the antifouling performance of PVDF membrane, a novel zinc sulfide/graphene oxide/polyvinylidene fluoride (ZnS/GO/PVDF) composite membrane was prepared by immersed phase inversion method. The surface morphology, crystal structure, photocatalytic activity, and antifouling property of the as‐prepared membranes were systematically studied. Results showed that the ZnS/GO/PVDF hybrid membranes were successfully fabricated with uniform surface. The hybrid membrane surface possessed higher hydrophilicity with water contact angle decreasing from 77.1° to 62.2°. The permeability of the hybrid membrane was therefore enhanced from 222.9 to 326.1 L/(m2 hour). Moreover, bovine serum albumin (BSA) retention experiment showed that the hybrid membrane separation was also promoted by 7.2%. The blending of ZnS and GO enhanced the hydrophilic and photocatalytic performances of PVDF membrane, which mitigated the membrane fouling effectively. This novel hybrid membrane could accelerate the practical application of photocatalytic technology in membrane separation process. [ABSTRACT FROM AUTHOR] |
