A reusable electrospun PVDF-PVP-MnO2 nanocomposite membrane for bisphenol A removal from drinking water

In this study, polyvinylidene fluoride (PVDF) nanocomposite membranes with different fillers were fabricated using electrospinning technique. The physico-chemical properties of electrospun membranes such as PVDF (NF1), PVDF-polyvinyl pyrrolidone (PVP) (NF2), PVDF-activated carbon (AC) (NF3), PVDF-Mn...
