      abstract     = {Two imidazolium based graft-type of anion-conducting
                      electrolyte membranes (AEMs) for fuel cells with a moderate
                      ion exchange capacity of ∼1.0 mmol/g were successfully
                      prepared by radiation-induced grafting to introduce
                      imidazolium and styrene units into a
                      poly(ethylene-co-tetrafluoroethylene) (ETFE) base film.
                      Though imidazolium groups were desired to connect with
                      styrene groups via two different ways, i.e. parallel or
                      perpendicular orientations to the graft-polymer chains via
                      copolymerization (AEM1) or homo-polymerization (AEM2), both
                      AEMs possess high ion conductivity (>100 mS/cm at
                      60 °C) and modest stability. The morphologies of these
                      membranes were elucidated by small-angle neutron scattering
                      method. Our results revealed that 1) both AEMs show clear
                      microphase separation with a length scale of 30–40 nm,
                      and the semi-crystalline structural feature of the
                      hydrophobic microdomains contributes to the membrane
                      mechanical property; 2) at the length scale <6 nm, ionic
                      structures of the two AEMs are different: Parallel type of
                      AEM1 shows a homogeneous distribution of ions in the ion
                      channel; while perpendicular type of AEM2 shows ionic
                      clusters nanophase-separated from the graft polymers.},
