Abstract: A capacitive deionization apparatus may include at least one pair of porous electrodes and a spacer structure disposed between the at least one pair of electrodes. The at least one pair of porous electrodes may include an electrode material having a surface area for the electrostatic adsorption of feed ions. The spacer structure may include an electrically-insulating material with an ion exchange group on the surface thereof. The spacer structure provides a path for flowing a fluid therethrough.

Abstract: The present disclosure relates to a spacer structure that is configured to be disposed between a pair of electrodes in a capacitive deionization apparatus so as to provide a space for flowing a fluid therethrough. The spacer structure includes a copolymer prepared by copolymerizing a mixture of a polyurethane backbone including a carboxyl group or a sulfonic acid group, an ion conductive monomer including a carboxyl group and a cation exchange group, and a second polymer including a functional group that reacts with the carboxyl group or sulfonic acid group and forms a cross-linking bond with the polyurethane backbone.
