Polymers functionalised with aliphatic mono- and spirocyclic quaternary ammonium cations for anion exchange membranes
Different approaches to anion exchange membranes (AEMs) are currently intensively investigated with the aim to develop materials for application in electrochemical energy devices such as alkaline fuel cells and electrolysers.1 One of the major challenges is to identify feasible synthetic strategies to AEM materials with sufficient long-term chemical and thermal stability. Studies of different smal
