 note = {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 waterrich 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%.},
