Claim 0:
1. An anion exchange membrane comprising:
a) an anion exchange polymer comprising:
i) polyphenylenes homopolymer backbones with side chain consisting of hydrophilic side chains with a CF3 linkage to said backbone; and
ii) said hydrophilic side chains being linear hydrocarbon side chains having functional groups;
wherein the anion exchange polymer extends as a first surface layer on a first side and as a second surface layer on a second side, opposing said first side, of the anion exchange membrane;

b) a functional additive configured within the anion exchange membrane, between said first surface layer of said anion exchange polymer and said second surface layer of said anion exchange polymer, wherein the functional additive comprises a radical scavenger comprising polydopamine.
