A novel approach is proposed to design AEMs with flexible ether-containing side chain. Enhanced mobility of side chains and ion interactions promote micro-phase separation. Conductivity (72 mS cm−1) and swelling (7.3%) are well balanced even at 60 °C. Good alkaline stability (60 °C, 1 M KOH for 168 h) is obtained.
