First Claim
Patent Images
1. A membrane having a first surface and a second surface, the membrane comprising one or more anionic exchange electrolyte polymers;
- wherein the one or more anionic exchange electrolyte polymers comprise a plurality of contiguous domains, wherein the plurality of contiguous domains comprise at least a first contiguous domain and at least a second contiguous domain that are phase separated;
wherein the first contiguous domain comprises a plurality of repeat units having moieties with electrostatically bound negative ions and covalently bound positive ions;
wherein the second contiguous domain comprises a plurality of repeat units with non- charge bearing moieties; and
wherein at least a portion of the first contiguous domain or at least a portion of the second contiguous domain extends from the first surface of the membrane to the second surface of the membrane.
