Radiation-induced grafting of a butyl-spacer styrenic monomer\ud onto ETFE: the synthesis of the most alkali stable radiationgrafted\ud anion-exchange membrane to date

摘要

An ETFE-(poly(ethylene-co-tetrafluoroethylene))-based radiationgrafted\udanion-exchange membrane (AEM) containing a butylspacer\udbetween the benzene and the methylpyrrolidinium groups\ud(C4-AEM) had double the ex-situ alkali stability at 80 °C compared\udto a methylene benchmark (C1-AEM). H2/O2 fuel cells containing\udthe C4-AEM still achieved a peak power density of > 1 W cm-2.
