Application of high-dispersity hybridization antibacterial agent in aspect of ultrafiltration membrane improvement

The invention discloses application of a high-dispersity hybridization antibacterial agent in aspect of ultrafiltration membrane improvement. The high-dispersity hybridization antibacterial agent is a nanometer hybridization material formed by anchoring silver nanoparticles to a graphene slice layer. The application of the high-dispersity hybridization antibacterial agent for ultrafiltration membrane improvement comprises the steps that firstly, the high-dispersity hybridization antibacterial agent is added into N,N dimethylacetamide or N,N dimethylformamide or dimethyl sulfoxide, ultrasonography is performed to obtain a uniform dispersion agent, polyvinylidene fluoride or polyether sulfone is added into the dispersion agent, stirring is performed at the temperature of 55-65 DEG C to obtain a uniform casting membrane solution, standing is performed for defoaming for 6-12 h, pure water is adopted as a coagulation bath, and an immerged phase-inversion method is adopted for preparing a modified ultrafiltration m
