Multi‐permselective membranes with diffusivity‐selectivity, solubility‐selectivity, and reactivity‐selectivity for CO 2 separation are prepared by interfacial polymerization. The membranes are able to efficiently separate CO 2 from various light gases (H 2 , CH 4 and N 2 ) due to the optimized membrane structure and the comprehensive utilization of distinctions between CO 2 and light gases in size, condensability, and reactivity.
