Abstract :
Water vapour sorption kinetics in a H+ form naphtalenic sulfonated polyimide membrane at 25°C has been investigated by using an electronic microbalance (IGA, Hiden). An effective diffusion coefficient Dexp has been calculated from kinetic data by using the Fickian model for the final part of the sorption. The variation of Dexp with the equilibrium water activity (0
