Abstract

original image

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 (H2, CH4 and N2) due to the optimized membrane structure and the comprehensive utilization of distinctions between CO2 and light gases in size, condensability, and reactivity.
