Abstract :
The permeability of gases through thin polyaniline EB film depends upon the combined mobility and solubility of the gases at a given temperature and pressure. The gas transport behavior of an emeraldine base (EB) film was studied in detail. Permeability measurements were made using the manometric time-lag method of analysis for He, H2, CO2, O2, N2 and CH4, all as functions of varying temperature (15° to 40° C). These measurements allowed us to determine the activation energies for permeation, diffusion, and heat of solution for each gas tested. Permeability of the gases is temperature dependent, permeability increases with increasing temperature and permselectivity of the gas pairs He/N2, O2/N2, CO2/CH4 decreases with increasing temperature.
