a) Sorption isotherms for CO2, CH4 and N2 in MeOH treated PIM-Trip-TB film of 132 μm thickness. Thin solid lines represent the fit of the data according to the dual mode sorption model and thick solid lines represent the corresponding ideal sorption selectivity calculated from the curve fit. b) Relative differences in sorption of CO2, CH4 and N2 between MeOH treated films of PIM-Trip-TB and PIM-EA-TB. Positive values indicate a pressure where gas sorption in PIM-Trip-TB is higher than that of PIM-EA-TB.
