Abstract
An anion exchange ionomer is disclosed that contains a fluorinated, ether-free backbone, and a fluorinated ether based quaternary ammonium functional group. The novel polymer has improved chemical and mechanical stability as compared to the state-of-the-art materials for incorporation in anion exchange membrane. The disclosed anion exchange ionomer may be incorporated into an anion exchange membrane and used in electrochemical applications.
