摘要:
Anion exchange polymers having high OH− conductivity, chemical stability, and mechanical stability have been developed for use in AEMs. The anion exchange polymers have stable hydrophobic polymer backbones, stable hydrophilic quaternary ammonium cationic groups, and hydrophilic phenolic hydroxyl groups on the polymer side chains. The polymers have polymer backbones free of ether bonds, hydrophilic polymer side chains, and piperidinium ion-conducting functionality, which enables efficient and stable operation in water or CO2 electrolysis, redox flow battery, and fuel cell applications. The polymer comprises a plurality of repeating units of formula (I) Anion exchange membranes and membrane electrode assemblies incorporating the anion exchange polymers are also described.
