Abstract

Recently, many applications with grapheneoxide (GO) have been reported. But GO membrane for water treatmenthas not been developed. In this study we prepared polyvinylidene difluoride (PVdF) nanofiber/GO hybrid membrane(FG) for the microfiltration application. The PVdF substrate membrane was prepared by using the electrospinning methodwith a solution of PVdF in N,N-dimethylacetamide (DMAc) and acetone. GO sheets used in this study were prepared bymodified Hummer’s method. The PVdF/GO hybrid membrane was finally prepared by spraying the GO solution dispersedin ethanol on the PVdF nanofiber. The successfully prepared FG was thoroughly examined by SEM, Raman, contact angle,porometer and UTM, and water-flux was measured with designed cell (Dead-End Cell). From the contact angle results, itwas found that the surface of FG membrane was reformed by hydrophilic property and the water permeability was increasedabout 2.5 times than that of the nascent PVdF membrane, indicating the possible alternative of the commercial MFmembrane.
