Abstract
Anion exchange membranes (AEMs) for separators in electrochemical devices and methods for making same are disclosed herein. AEMs include chloromethylated SEBS triblock copolymer functionalized with TRIS cations and chloromethylated QPEK-C functionalized with TMA cations. Composite AEMs further include metal oxide fillers. Reinforced AEMs and reinforced composite AEMs further include a reinforcement material base.
Claims15
An anion exchange membrane (AEM) comprising:
- a chloromethylated polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene (SEBS) triblock copolymer functionalized with Tris(2,4,6-trimethoxyphenyl) phosphine (TRIS) cations;
- and
- wherein the triblock copolymer is fully functionalized with the Tris(2,4,6-trimethoxyphenyl) phosphine (TRIS) cations.
