Non-fluorinated polymer membranes offer a commercially feasible solution for redox flow batteries (RFBs), yet their practical applications have been hampered by inherent challenges such as chemical instability and low ionic conductivity. In this study, the development of a series of ether-bond-free poly(aryl piperidine) membranes that address these limitations by introducing enhanced disorder in polymer chain packing through supramolecular interactions with organic acids, is presented. These interactions effectively disrupt densely packed polym...
