Antibacterial and Adsorption Properties of Sulfonated GO-PVDF Nanocomposite Ultrafiltration Membranes for Environmental Applications

AbstractThe application of nanocomposite materials in membrane bioreactors (MBRs) is attractive because of their great potential to enhance the filtration performance and antifouling. This study modified polyvinylidene fluoride (PVDF) ultrafiltration membranes using graphene oxide (GO) and sulfonati...

Zusammenfassung:	AbstractThe application of nanocomposite materials in membrane bioreactors (MBRs) is attractive because of their great potential to enhance the filtration performance and antifouling. This study modified polyvinylidene fluoride (PVDF) ultrafiltration membranes using graphene oxide (GO) and sulfonation GO (SGO). The antibacterial properties of nanocomposite membranes were tested using three Gram-negative bacterial species (Pantoea agglomerans, Escherichia coli, and Pseudomonas graminis). The results showed that PVDF-GO and PVDF-SGO ultrafiltration (UF) membranes had significantly nontoxic properties (>95%, significance at p
