A series of novel blended anion exchange membranes (AEMs) were prepared with hyperbranched brominated poly(arylene ether sulfone) (Br-HB-PAES) and linear chloromethylated poly(phenylene oxide) (CM-PPO). The as-prepared blended membranes were fabricated with different weight ratios of Br-HB-PAES to CM-PPO, and the quaternization reaction for introducing the ionic functional group was performed by triethylamine. The Q-PAES/PPO-XY (quaternized-PAES/PPO-XY) blended membranes promoted the ion channel formation as the strong hydrogen bonds interconnecting the two polymers were maintained, and showed an improved hydroxide conductivity with excellent thermal behavior. In particular, the Q-PAES/PPO-55 membrane showed a very high hydroxide ion conductivity (90.9 mS cm-1) compared to the pristine Q-HB-PAES membrane (32.8 mS cm-1), a result supported by the morphol. of the membrane as determined by the AFM anal. In addition, the rigid hyperbranched structure showed a suppressed swelling ratio of 17.9-24.9% despite an excessive water uptake of 33.2-50.3% at 90°C, and demonstrated a remarkable alk. stability under 2.0 M KOH conditions over 1000 h. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Related Products of 80-07-9
