Precise manipulation of the polyelectrolyte self-assembly process, to form the desired microstructure with ion-conducting channels, is of fundamental and technol. importance to many fields, such as fuel cells, flow batteries and electrodialysis. To fabricate anion exchange membranes (AEMs) with highly conductive and alk. stable ion-conducting channels, we hereby report a strategy for designing self-aggregating side chains with optimized alk. stability, by inserting dipolar ethylene oxide (EO) spacers in the cationic side chain. Simulation and nano-scale microscopy analyses verify the self-assembly process of the flexible side chain with cation-dipole interaction to construct interconnected ionic highways for fast water and ion transportation. The resulting O-PDQA AEM exhibits higher hydroxide conductivity (106 mS cm-1 at 80 °C) and a competitive peak power d. (1.18 W cm-2 at 70 °C) in alk. H2/O2 single-cell fuel cells. Moreover, O-PDQA shows excellent alk. stability with over 96% conductivity retention after storage in 2 M NaOH solution at 80 °C for 1080 h. This new concept of introducing dipolar moieties in the cationic side chain can accelerate the development of technologies that involve polyelectrolytes. The experimental part of the paper was very detailed, including the reaction process of 1-Methyl-4-piperidone(cas: 1445-73-4Computed Properties of C6H11NO)
1-Methyl-4-piperidone(cas: 1445-73-4) is a member of piperidine. Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Hence, continuous efforts have been made to develop convenient methods to prepare piperidine derivatives.Computed Properties of C6H11NO
