AB  - To ameliorate the trade-off effect between ionic conductivity and water swelling 
      of anion exchange membranes (AEMs), a crosslinked, hyperbranched membrane (C-HBM) 
      combining the advantages of densely functionalization architecture and 
      crosslinking structure was fabricated by the quaternization of the hyperbranched 
      poly(4-vinylbenzyl chloride) (HB-PVBC) with a multiamine oligomer 
      poly(N,N-Dimethylbenzylamine). The membrane displayed well-developed microphase 
      separation morphology, as confirmed by small angle X-ray scattering (SAXS) and 
      transmission electron microscopy (TEM). Moreover, the corresponding high ionic 
      conductivity, strongly depressed water swelling, high thermal stability, and 
      acceptable alkaline stability were achieved. Of special note is the much higher 
      ratio of hydroxide conductivity to water swelling (33.0) than that of most 
      published side-chain type, block, and densely functionalized AEMs, implying its 
      higher potential for application in fuel cells.
