摘要:

 高堿穩定性、高離子電導率的陰離子交換膜的設計與制備是近年來燃料電池領域研究的前沿和熱點。本文從分子設計出發,聚合物主鏈上引入優異穩定性氟原子的基礎上,在側基上進行功能基團的嫁接,合成了嗎啉、直鏈季銨、咪唑型的全氟陽離子聚合物,并將這些聚合物制成相應的陰離子交換膜。結果顯示:所得三種陰離子交換膜在80 ℃水中的離子電導率為60.4~80.6 mS/cm之間,其中,直鏈季銨型陰離子交換膜在80℃下的電導率達到了 80.6 mS/cm。此外,在 80 ℃,8M KOH 水溶液中浸泡 10 天后,離子膜的IEC和電導率分別保留了 92.7 %和 93.2 %,表現出了優異的耐堿性能。

 Design and fabrication of high alkaline stability and high ionic conductivity of anion exchange membranes are one of the frontier and hot research areas of fuel cells in recent years. A new research program is proposed, which mainly focuses on molecule synthesis to design and prepare a series of perfluorinated cationic polymers and their AEMs, including linear-quaternary-ammonium, cyclic-morpholine and imidazole-functionalized cationic polymers were successfully synthesized by incorporation of excellent stability fluorine atoms in the polymer main chain and utilization the pendant groups to attach various functional groups. The resulted AEMs displayed the high conductivity of 60.4~80.6 mS/cm at 80 ?C in water. Additionally, linear-quaternary-ammonium membrane exhibited good hydroxide conductivity of 80.6 mS/cm at 80 °C and excellent dimensional stability in water. Moreover, the membrane maintained 92.7% IEC and 93.2% hydroxide conductivity value after immersion in 8 M KOH at 80 °C over ten days and exhibits good alkaline stability.
