Chitosan-Modified Poly(2,6-dimethyl-1,4- phenylene Oxide) for Anion-Exchange Membrane in Fuel Cell Technology Myint Myint Khaing Chen, Nanjun Long, Chuan Li, Yunxi Wang, Fanghui Zhu, Hong 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% chitosanmodified 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. 2018 http://hdl.handle.net/20.500.12678/0000000994 https://meral.edu.mm/records/994
