Abstract：

High permeability and selectivity PEBA/EPH gel membranes were prepared by solvent evaporation method. The effect of EPH content on the microstructure, properties and performance of these gel membranes was discussed. Added by EPH, a favorable mechanical property of PEBA/EPH gel membranes was showed with an obvious increase of membrane density and a decrease of relative crystallinity. The increase of EPH content leaded to a significant increase in permeability coefficients of CO2 and the ideal selectivity of CO2/N2. When the EPH content increased to 60 wt%, the CO2 permeability improved to 352.96 barrer and the ideal selectivity of CO2/N2 reached to 85.67.
