Synthetic Approaches to Poly(arylene alkylene) Anion-exchange Membranes

10th Forum on New Materials
- Abstract
- Extensive research is currently being conducted to develop anion exchange membranes (AEMs) with high hydroxide conductivity and chemical stability, aiming to increase efficiency and lifetime of alkaline membrane fuel cells, water electrolyzers, and flow batteries. In this context, poly(arylene alkylene)s have recently emerged to offer great opportunities and flexibility to molecularly design and prepare tunable and robust AEMs with high performance and longevity. This class of polymers is prepared by superacid-mediated Friedel-Crafts-type polyhydroxyalkylations, typically involving a ketone or an aldehyde, and an arene such as biphenyl and terphenyl. My research group has over the past 8 years studied poly(arylene alkylene)s and has, for... (More)

My research group has over the past 8 years studied poly(arylene alkylene)s and has, for example, reported on the synthesis and properties of different poly(aryl piperidinium) AEMs, demonstrating high alkaline stability and hydroxide conductivity. In the current presentation, I will discuss some of our recent synthetic strategies to tune and improve the preparation, properties, and performance of poly(arylene alkylene) AEMs functionalized with N-alicyclic quaternary ammonium cations.
