Anionic exchange electrolyte polymer membranes

摘要

The present disclosure provides a membrane having a first major surface and a second major surface and including one or more anionic exchange electrolyte polymers. The membranes can be useful for selectively mass transporting molecules and/or ions.

主权项

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.
