520	3		_aTransport rates (permeability)and ideal separation factors for several gas pairs through dense polyaniline membranes are reported. The ideal separation factors for all gas pairs tested were found to be independent of the polyaniline membrane thickness whereas the permeability of the single gases showed significant variations. Both dedoped and redoped films (film thickness between 9 and 67 m)were studied. The highest selectivities (A/B)found were 7.6 for the gas pair H2/CO2 in the case of the dedoped membrane and 10 for the gas pair H2/CO2, 6 for O2/N2 and 200 for H2/N2 in the case of the redoped membrane. Statistical analysis of a large number of membranes allowed the critical comparison with results obtained by other groups. Comparison with other membrane materials shows that an approximately sixfold enhancement of the respective separation factors is possible for gas pairs containing hydrogen. Similar separation factors are observed for the gas pairs CO2/O2, CO2/N2 and N2/O2.
