Preparation and properties of PPSU/GO mixed matrix membrane

With the addition of nano graphene oxide, the anti fouling performance of PPSU/GO membrane is improved. When the GO addition is 1.5%, the flux recovery rate of PPSU/GO mixed matrix membrane reached the maximum of 86%, and the total pollution number and irreversible pollution parameters decreased. Because GO into hydrophilic groups, water molecules will preferentially combine with the polar groups on the membrane surface, forming a hydration layer, played a blocking role in pollutants, thereby reducing the total membrane pollution and reversible pollution.171
