摘要：

Graft-type anion-conducting polymer electrolyte membranes (AEMs) are prepared by the radiation-induced graft polymerization of chloromethylstyrene into poly(ethylene-co-tetrafluoroethylene) (ETFE) films and subsequent quaternization with trimethylamine. AEMs in the hydroxide form (AEM-OH) are prepared by immersing the chloride form (AEM-Cl) in 1 M potassium hydroxide (KOH) solution, followed by KOH and washing with nitrogen-saturated water to prevent bicarbonate formation (AEM-HCO3). The AEM-OH shows conductivity and water uptake four and two times higher than AEM-Cl and -HCO3 and is thermally and chemically less stable, resulting in the tendency to absorb water and to convert to the bicarbonate form.
