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.}, pages = {619--627}, publisher = {The Electrochemical Society}, title = {Imidazolium-Based Grafted Anion Exchange Membranes: Interplay between the Morphology and Anion Transport Behavior}, volume = {86}, year = {2018} }
