Description
Graft-type anion-conducting electrolyte membranes with aniline groups (aniline-AEM) were synthesized through radiation-induced graft polymerization of N,N-dimethylaminostyrene (DMASt) on poly(ethylene-co-tetrafluoroethylene) (ETFE), followed by N-methylation and ion-exchange reactions. The obtained aniline-AEM with ion-exchange capacities (IECs) of 0.67-1.86 mmol/g showed conductivity of 53-213 mS/cm at 60 °C and water uptake of 18-118%. Aniline-AEM exhibited excellent alkaline stability by maintaining the conductivity 70 mS/cm in 1 M KOH at 80 °C for 168 h.
