摘要
An antifouling and hydrophilic polyethersulfone ultrafiltration membrane and a preparation method therefor. By using a Co-γ radiation grafting chemical modification method, an unsaturated bond-containing ionic liquid linked by chemical bonds is uniformly distributed on the surface of polyethersulfone, and then an asymmetric porous membrane is prepared by using an immersion precipitation phase inversion method, a mass ratio of the ionic liquid to the polyethersulfone being 2-11:100. The ultrafiltration membrane is an asymmetric porous membrane, and has excellent antifouling properties, good pure water flux and a good BSA rejection rate.
