Fabrication of sulfonated polyethersulfone ultrafiltration membranes with an excellent antifouling performance by impregnating with polysulfopropyl acrylate coated ZnO nanoparticles

Sulfonated polyethersulfone/sulfopropyl methacrylate membranes impregnated with the polysulfopropyl acrylate coated ZnO nanoparticles were developed using a non-solvent-induced phase separation recipe. The composite offered much-enhanced hydrophilicity and improved porosity, which are critical for excellent antifouling performance high permeate flux. By adding modified ZnO, it achieved maximum water flux of 420 Lm?2h?1 while maintained natural organic matter rejection rate 99% an recovery ratio up to in measurement. results display that impregnation sulfonated polyethersulfone membrane can effectively increase surface is essential reducing irreversible fouling long-term recyclability.
