      Microphase Separated Morphology for Alkaline Fuel Cells.

AB  - It is well acknowledged that the microphase-separated morphology of anion 
      exchange membranes (AEMs) is of vital importance for membrane properties utilized 
      in alkaline fuel cells. Herein, a rigid macromolecule poly(methyldiallylamine) 
      (PMDA) is incorporated to regulate the microphase morphology of hyperbranched 
      AEMs. As expected, the hyperbranched poly(vinylbenzyl chloride) (HB-PVBC) is 
      guided to distribute along PMDA chains, and longer PMDA cha leads to a more 
      distinct microphase morphology with interconnected ionic channels. Consequently, 
      high chloride conductivity of 10.49 mS cm(-1) at 30  degrees C and suppressed water 
      swelling ratio lower than 30% at 80  degrees C are obtained. Furthermore, the beta-H of 
      pyrrolidinium cations in the non-antiperiplanar position increases the energy 
      barrier of beta-H elimination, leading to conformationally disfavored Hofmann 
      elimination and increased alkaline stability. This strategy is anticipated to 
      provide a feasible way for preparing hyperbranched AEMs with clear microphase 
      morphology and good overall properties for alkaline fuel cells.
