  • CERAMIC GO/PEI NANOMEMBRANE BY LAYER-BY-LAYER ASSEMBLY BASED ON COVALENT BOND USING EDC CHEMISTRY AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20220194869
    Abstract: The present disclosure relates to a ceramic graphene oxide nanofiltration membrane which is high in mechanical stability while having ion removal ability by alternately stacking GO and PEI on a ceramic nanomembrane by allowing a carboxyl group (—COOH) and an amine group (—NH2) to form a covalent bond in the presence of N-ethyl-N?-[3-(dimethylamino)propyl]carbodiimide hydrochloride (EDC), thereby forming an amide group (—CONH), and a method for manufacturing the same.
