Abstract: Based on the superior CO2 separation performance and tunable physicochemical nature of poly(ionic liquid) (PIL),a series of gas separation membranes with semi-interpenetrating polymer network (semi-IPN) structure were successfully synthesized from Pluronic F127 and crosslinked PIL.Compared with Pluronic F127,the obtained F127/PIL semi-IPN membranes displayed much improved mechanical strength and good film-forming property.The tensile strength of membranes containing 70% PIL was 4.569MPa.From gas permeation measurement results,the membranes demonstrated gradually higher CO2 permeability coefficient with the increase of PIL content,while CO2/N2 selectivity increased initially and then decreased slightly.The best CO2 permeability and CO2/N2 selectivity of membranes reached 155.59 Barrer and 24.16 respectively when PIL content was 80wt%.Moreover,the permeability of CO2 in membranes increased with increasing temperature across their glasstransition temperatures,while CO2/N2 selectivity decreased.
