▎ 摘　　要

NOVELTY - Preparation of dopamine-assisted dispersive graphene oxide-modified polyvinylidene fluoride ultrafiltration membrane involves adding sheet of graphene oxide and dopamine to N,N-dimethylacetamide, ultrasonically dispersing, adding polyvinylpyrrolidone and polyvinylidene fluoride particles, stirring to obtain a casting solution, and forming ultrafiltration membrane by subjecting the casting solution to immersion-precipitation phase inversion method. USE - Preparation of dopamine-assisted dispersive graphene oxide-modified polyvinylidene fluoride ultrafiltration membrane. ADVANTAGE - The dopamine-assisted dispersive graphene oxide-modified polyvinylidene fluoride ultrafiltration membrane having excellent antifouling property and water flux is produced. The graphene oxide dispersion is made stable by adding dopamine, and hydrophilic modification effect is increased.
