A mechanically strong and tough anion exchange membrane engineered with non-covalent modalities

摘要

A mechanically robust and tough anion exchange membrane was constructed using the strategy of supramolecular modalities. After introducing a secondary amide as a hydrogen-bonding crosslinking motif into the side chain of the PPO backbone, the membrane exhibits high mechanical strength and excellent flexibility (101 elongation at break), as well as suppressed water uptake, enhanced thermal stability and good fuel cell performances.
