Fabrication of Anion-Exchange Polymer Layered Graphene–Melamine Electrodes for Membrane Capacitive Deionization

A novel nitrogen-doped reduced graphene sponge composite (NRGS) is fabricated by using melamine sponge to restrain the aggregation of graphene sheets during reduction. The anion-exchange polymer layered graphene composites (A-NRGS) are prepared by coating the surface of the NRGS electrode with cross-linked poly(vinyl alcohol) with quaternization modification (C-qPVA). With the help of a melamine sponge to suppress the agglomerate of graphene...
