▎ 摘　　要

NOVELTY - Preparation of nano-silver/graphene/polyvinylidene fluoride hybrid ultrafiltration membrane involves uniformly mixing solution (A) obtained by ultrasonically dispersing graphene oxide and polyethylene glycol in N,N-dimethylacetamide, and solution (B) obtained by dissolving silver nitrate and polyethylene glycol in N,N-dimethylacetamide, obtaining nano silver/graphene composite solution, adding polyvinylidene fluoride, mixing, maintaining, defoaming, obtaining casting solution and performing precipitation phase-inversion process. USE - Preparation of nano-silver/graphene/polyvinylidene fluoride hybrid ultrafiltration membrane (claimed). ADVANTAGE - The method provides nano-silver/graphene/polyvinylidene fluoride hybrid ultrafiltration membrane having excellent antibacterial performance, by environmentally-friendly process.
