Abstract

An ion exchange membrane is provided which includes an ion exchange polymer that is partially cross-linked. The partially cross-linked ion exchange polymer will be more stable and will not be washed out over time. The ion exchange polymer may be UV or chemically cross-linked, wherein a cross-linking compound is added to the ion exchange polymer either before or after coupling to a support material. A support material may be made of, or be coated with, a cross-linking compound and the support material may initiate cross-linking proximal to the support material. The support material may be made of a material that chemically bonds with the ionomer.
