Carbon monoxide (CO) is an important raw material in chemical industries; however, its separation through solid-state polymer membranes has not been extensively investigated. Herein, a series of comb-like copolymers is synthesized and used as a matrix to incorporate AgBF4 and ionic liquid ([bmim][BF4]) for solid-state facilitated CO transport membrane. The CO/N2 separation performance is improved by introducing AgBF4 together with [bmim][BF4] into the copolymer matrix. Incorporating AgBF4 significantly increases the interaction energy between the membrane and CO molecules, demonstrating that Ag salts act as facilitated CO transport carriers and increase CO solubility in the membrane. Results show that the ionic liquid prevents comb copolymer aggregation and improves CO/N2 selectivity. |
