This paper reports the transport and sorption properties of poly(fluoroalkoxyphosphazene) (PFAP) membranes for carbon dioxide and nitrogen in both pure and mixed gas experiments. The CO2 permeability decreased from 336 to 142 Barrers with an increase in the CO2/N2 ideal separation factor from 12 to...
