Abstract
Provided is a nanocomposite ultrafiltration membrane including a hydrophobic polymer matrix impregnated with graphene oxide or reduced graphene oxide. The PAN/GO nanocomposite ultrafiltration membrane has improved mechanical properties, high permeability and a high salt rejection ratio, and excellent anti-fouling property and durability. Thus, the nanocomposite ultrafiltration membrane may be manufactured in the form of a membrane module applied to a water treatment system so that it may be utilized in an actual ultrafiltration separation process.
