摘要
Multi-permselective membranes with diffusivity-selectivity, solubility-selectivity, and reactivity-selectivity for CO2 separation are prepared by interfacial polymerization. The membranes are able to efficiently separate CO2 from various light gases (H-2, CH4 and N-2) due to the optimized membrane structure and the comprehensive utilization of distinctions between CO2 and light gases in size, condensability, and reactivity.
