Abstract:
The ionic conductivity of a polyelectrolyte membrane consisting of 30 bilayers of poly(allylamine hydrochloride) and p‐sulfonato‐calix[8]arene, (PAH/calix8) 30 , is investigated for two alkali ions, i.e., Li + and Rb + . Two different transport pathways, a fast and a slow one, are identified for Li + transport. By contrast, only the fast transport pathway is observed for Rb + transport. This fast transport pathway is assigned to regular hopping through bulk material, whereas the slow transport pathway originates from retarding interaction with the calixarene rings, only operative for Li + but not for Rb + . This observation constitutes a clear manifestation of ionic selectivity for transport in polyelectrolyte membranes.
