Abstract
In this study, the nanofiber composite membrane was prepared by electrospinning method with poly(ancrylonitrile) (PAN) and a dispersed solution of graphene oxide (GO) and Fe3O4functionalized graphene oxide (M-GO) indimethyl formamide (DMF). The pore-diameter of prepared membranes was controlled by change of those layers. It wasconfirmed with SEM that the nanofiber composite membranes having fiber size of 500 nm were prepared. It was found withRaman spectroscopy and EDS that GO and M-GO were well dispersed on those membranes. Final nanofiber compositemembrane showed the similar pore properties (0.21~0.24 μm/pore-size, 40% porosity) with the commercial membrane (0.27μm/pore-size, 55% porosity) and their water-flux results also showed the 200% higher flux than its PAN membrane. Fromthese results, it was expected that the nanofiber composite membrane prepared by electrospinning method could be utilizedas a water-treatment membrane.
