Biofouling is a major concern in membrane filtration which could adversely have an effect on the overall membrane performance. To address this issue herein, we prepared polyethylenimine-grafted graphene oxide (GO-PEI) as a filler material to be used in the sulfonated polysulfone membrane (SPES). The PEI grafting on GO and successful sulfonation of PES was confirmed… Continue reading Biofouling Mitigation Using Graphene Oxide Functionalized Polyethylenimine/Sulfonated Polysulfone Composite Membranes
