Antibacterial studies of Ag@HPEI@GO nanocomposites and their effects on fouling and dye rejection in PES UF membranes.

ABSTRACT: A series of polyethersulfone membranes containing Ag@HPEI@GO composite was fabricated using non-solvent induced phase separations (NIPS) to mitigate against biofilm causing bacteria and modulate solute rejection. All materials produced and used were fully characterised using a combination of appropriate physicochemical techniques including FTIR, XRD, BET, SEM, AFM. The GO-based fillers exhibited bactericidal activities. The bactericidal activities of GO, HPEI@GO against Escherichia Coli (E. coli) were observed at 8 mg mL^-1 whilst Ag@HPEI@GO composites exhibit bactericidal activities against E. coli at 4 mg mL^-1. Against Klebsiella pneumonia (K. pneumonia), GO bactericidal activities were observed at 8 mg mL^-1, whilst HPEI@
