Abstract:Acid‐functionalized polymers enhance the performance of phosphoric‐acid‐doped polybenzimidazoles (PA/PBIs); however, studies on examining the mechanisms driving these enhancements are scarce. Furthermore, the nanophase morphology of PA‐dependent proton‐exchange membranes has been rarely explored, despite its direct role in the distribution of PA and protonic conduction. In this study, theoretical and experimental analyses to evaluate the microphase separation, particularly the formation and in situ transformat… Show more
