To improve the hydrophilicity and long-lasting bacterial inhibition of poly(vinylidene fluoride) (PVDF) ultrafiltration membranes, DA/Ag-GO/PSF/PVDF hybrid ultrafiltration membranes were prepared with PVDF and polysulfone (PSF) as substrates, graphene oxide (GO) as additives, and dopamine (DA) and silver as surface modifications. The structure and performance of PSF/PVDF hybrid membranes were investigated by SEM, FTIR, contact angle, filtration flux, and bacterial inhibition tests. The results showed that with the addition of GO, the hydrophilicity of the PSF/PVDF hybrid membranes were enhance...
