Alkaline anion exchange membrane from poly(arylene ether ketone)-g-polyimidazolium copolymer for enhanced hydroxide ion conductivity and thermal, mechanical, and hydrolytic stability |
| 초록 |
a series of alkaline anion exchange membranes (AAEMs) are synthesized from poly(arylene ether ketone)-poly(vinyl-1-butylimidazolium) graft copolymers (PAEK-g-[PBVIm-OH]) with different [PBVIm-OH] cationic chain lengths. The PAEK-g-[PBVIm-OH]-based AAEMs show excellent hydroxide ion conductivity without sacrificing thermal, mechanical, and dimensional stability. The hydroxide ion conductivity increases with increasing PBVIm-OH graft chain length. The AAEM membrane with the longest PBVIm-OH chain length shows the highest hydroxide conductivity of 0.00878 S cm-1 at 40 oC and the highest elongation of 206.7 % in the hydrate state as well as the highest power density of 22 mW cm-2 at a current density of 55 mA cm-2, which is very promising for fuel cell applications. |
