| 内容記述 | In this report, the anion transport behavior of imidazolium-based graft-type anion exchange membranes (AEMs) having imidazolium (Im)/styrene (St) graft-copolymers was studied. We have reported the graft-copolymers coordinately form ion channels where dissociated ions are dispersed and the connectivity of channels increases with the increasing hydration number, (the number of water molecules per Im group). Here, we investigated the conductivity, water uptake, and anion diffusivity of AEMs with different grafting degrees (GDs) and different counterions as a function of . The plot of the ratio of the anion diffusion coefficient in AEMs to its diffusivity in the dilute solution (D/D0) with shows a superimposed master curve. This result strongly evidences that these AEMs have similar morphology relating to the anion transport, regardless of GDs and anion species. The findings in this study provide a guideline for future AEM design to enhance the ion transport efficiency. | |||||
