Polyelectrolyte-crosslinked graphene oxide-based cation exchange membrane and method of manufacturing the same

Abstract

Disclosed is a cation exchange membrane that has a structure in which a polymer is cross-linked to graphene oxide and can selectively restrict the permeation of anions. According to an embodiment of the present disclosure, a cation exchange membrane that has higher cation selectivity even at a thin thickness by cross-linking a polymer to graphene oxide and is not easily redispersed in water can be provided. In addition, the cation exchange membrane according to an embodiment of the present disclosure is much thinner than general commercial ion exchange membranes, thereby having low electrical resistance and flexibility. Accordingly, when used in desalination devices, fuel cells, etc., it can reduce the volumes and manufacturing costs of the products.
