View the Complete Application at the US Patent & Trademark Office
Provided herein are compositions, CO.sub.2-permeable/selective membranes and related methods of making and using the membranes. Ionically cross-linked poly(ether)-based membranes were prepared for applications relating to CO.sub.2. These films were studied for their thermal curing behavior using DSC. The resulting free-standing membranes have T.sub.gs near -64.degree. C., T.sub.dS up to 230.degree. C., and Young's modulus up to 4.2 MPa. These membranes showed CO.sub.2 permeabilities of 84-110 Barrer and CO.sub.2/N.sub.2 selectivity of 20-40.
