Synthesis and investigation of Poly(p-phenylene) based Multi-block Anion Exchange Materials (AEMs) with chain extender for Anion Exchange Membrane Fuel Cell |
| 초록 |
Anion exchange membranes (AEM) have been considered as one of the promising electrolytes for anion exchange membrane fuel cell (AEMFC). To realize high-performance for AEMFC, anion exchange membrane (AEM) required that excellent stability and high ion conductivity. Herein,we have synthesized aromatic multiblock copolymers consisting of poly(p-phenylene) blocks combined with hydrophobic poly(arylene ether sulfone) blocks using chain extender group for improve molecular weight which affecting the stability and performance of AEM. A series of multi-block poly(p-phenylene)s containing a quaternary ammonium group were synthesized by Ni(0)-catalyzed coupling reaction, benzylic bromination and in-situ quaternization, successively. In particular, we measured the chemical, mechanical stability and AEMFC performance of poly(p-phenylene) based ionomer. |
