POLYACRYLONITRILE/CHITOSAN COMPOSITE NANOFILTRATION MEMBRANE CONTAINING GRAPHENE OXIDE AND PREPARATION METHOD THEREOF

摘要

Provided is a polyacrylonitrile/chitosan composite nanofiltration membrane, including: a polyacrylonitrile support; and a chitosan coating layer modified with graphene oxide, or a polyacrylonitrile/chitosan composite nanofiltration membrane, including: a polyacrylonitrile support modified with graphene oxide; and a chitosan coating layer or chitosan coating layer modified with graphene oxide. The polyacrylonitrile/chitosan composite nanofiltration membrane containing graphene oxide shows high permeability and a high salt rejection ratio, has excellent anti-fouling property and chlorine resistance, and thus may be manufactured in the form of a spirally wound type membrane module applied to a water treatment system so that it may be utilized for an actual nanofiltration separation process.
