▎ 摘  要

NOVELTY - An antibacterial graphene oxide modified polyvinylidene fluoride hollow fiber membrane comprises 25-30 wt.% polyvinylidene fluoride, 1.5-3 wt.% graphene oxide, 0.5-1 wt.% composite coupling agent, 1-5 wt.% surfactant, 3-8 wt.% pore-forming agent, 8-16 wt.% hydrophilic agent and 39-63 wt.% solvent. USE - Antibacterial graphene oxide modified polyvinylidene fluoride hollow fiber membrane. ADVANTAGE - The product is easy to control, has high porosity, uniform pore diameter distribution, stable chemical property and catalytic anti-bacterial function, prevents proliferation of bacteria on membrane surface during sewage treatment process, accelerates pollutant oxidation decomposition, and improves anti-pollution property and filtering effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the antibacterial graphene oxide modified polyvinylidene fluoride hollow fiber membrane comprising vacuum drying graphene oxide, adding composite coupling agent and polyvinylidene fluoride, mixing to prepare dry powder, uniformly mixing surfactant, hydrophilic agent and solvent to obtain mixed solution, adding dry powder into mixed solution to form spinning solution, filtering and de-foaming, and pressurizing and forming.
