abstract = {Vinylbenzyltrimethylammonium hydroxide (VBA) and styrene
(St) cografted poly(ethylene-co-tetrafluoroethylene) anion
exchange membranes (VBA/St-AEM) were prepared by the
radiation-induced graft polymerization of
chloromethylstyrene and St and sequential quaternization and
anion exchange reactions. Increasing the St content in the
grafts to $63 \%$ resulted in a gradual $21 \%$ and
$34 \%$ decrease in the conductivity and water uptake,
respectively, compared to those in the VBA-homo-grafted AEM.
AEMs with a higher St content $(81 \%)$ showed a $9 \%$
and $18 \%$ higher conductivity and water uptake,
respectively. Small-angle neutron scattering showed that the
sudden growth of “water puddles” consisting of
water-rich nano-domains dispersed randomly in
phase-separated hydrophilic ion channels enhanced the
conductivity and water uptake. In the alkaline durability
test of VBA/St-AEM in 1 M potassium hydroxide at 80 °C
for 720 h, the loss of the conductivity was suppressed
from $43 \%$ to $8 \%,$ when the St contents in the
grafts were increased from $0 \%$ to $63 \%.$},
