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.
