Abstract

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.
