H+ and Na+ Ion Transport Properties of Sulfonated Poly(2,6-dimethyl-1,4- phenylenoxide) Membranes
Original language description
Diffusion coefficients of H+ and Na+ ions in sulphonated poly(2,6?dimethyl?1,4? phenylene oxide) (PPO) intermolecularly crosslinked with poly(2?butylaniline) (PBA) or poly?[2,2'-(m-phenylene)-5,5'-bibenzimidazole] (PBI) were evaluated from conductivity and H+/Na+ ion exchange measurements. Ion exchange capacity and transport properties of the PPO membranes with a degree of sulphonation higher than 29 % are comparable to those of Nafion. The observed deterioration of ion exchange capacity and ion transport with increasing content of the crosslinking agent is related to the partial occupation of the fixed sulpho- groups by the tertiary nitrogen groups present in the PBA and PBI.
