Abstract
An ion-exchange membrane is provided, and the fibers of the ion-exchange membrane are obtained by electrospinning. The electrospinning solution contains 100 parts by weight of polyvinyl alcohol (PVA), 10-100 parts by weight of a modifier, 10-100 parts by weight of an ion exchanger, and 100-2,500 parts by weight of water. The modifier has a reactive group that can react with the hydroxyl groups of the PVA. The ion exchanger has a polar functional group that can form hydrogen bonds with the hydroxyl groups of the PVA, and has an anion group that can provide ion-exchange ability.
