摘要

摘要采用Menshutkin反应制备了一系列交联壳聚糖修饰的季铵盐聚2,6-二甲基-1,4-苯基氧化物(CS-QAPPO)膜。将CS引入PPO主链后，CS- qappo膜的力学性能、尺寸稳定性和碱性稳定性均有明显改善。甚至，CS-QAPPO膜的氢氧根电导率也高于原始QAPPO膜。20%壳聚糖修饰的QAPPO膜性能最好，在90℃时氢氧化物电导率为32 mS cm−1。碱性稳定性测试表明，CS-QAPPO膜在2 M NaOH溶液中，在室温下放置2000 h后具有良好的化学稳定性。图形抽象

Chitosan-Modified Poly(2,6-dimethyl-1,4-phenylene Oxide) for Anion-Exchange Membrane in Fuel Cell Technology

ABSTRACT A series of cross-linking chitosan-modified quaternary ammonium poly(2,6-dimethyl-1,4-phenylene oxide)s membranes (CS-QAPPO) were prepared by the Menshutkin reaction. The mechanical property, dimensional stability, and alkaline stability of the CS-QAPPO membrane have been impressively improved by introducing CS into PPO backbone. Even the hydroxide conductivity of CS-QAPPO membranes is higher than that of the pristine QAPPO membrane. The 20% chitosan-modified QAPPO membrane shows the best performance, and the hydroxide conductivity is 32 mS cm−1 at 90°C. The alkaline stability measurements demonstrated excellent chemical stability of the CS-QAPPO membrane in 2 M NaOH solution at room temperature after 2,000 h. GRAPHICAL ABSTRACT
