Title: Ionic cross-linked polymeric films for gas separation

Abstract

Provided herein are compositions, CO2-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 CO2. These films were studied for their thermal curing behavior using DSC. The resulting free-standing membranes have Tgs near −64° C., TdS up to 230° C., and Young's modulus up to 4.2 MPa. These membranes showed CO2 permeabilities of 84-110 Barrer and CO2/N2 selectivity of 20-40.
