摘要
Abstract In this work, we report the synthesis of a new anion exchange membrane based on a Polyketone (PK) functionalized with 1‐(3‐aminopropyl)piperidine through a solvent‐less Paal‐Knorr reaction with a carbonyl (C CO %) conversion of 36%. A one‐step cast‐quaternization process by using 1,4‐diiodobutane was performed that yielded a homogeneous membrane in a highly reproducible way. The obtained membranes showed good performances in terms of thermal resistance (up to 250°C), water uptake of 21% and ion exchange capacity of 2 meq/g, which support their use as anion exchange membranes for water electrolysers (AEM‐WE).
