초록

The polymer electrolyte membranes, CL-SPEEK/Cellulose composite membrane I, II, III with the improved electrochemical and mechanical properties were prepared and characterized. The engineering plastic polyether ether ketone (PEEK) and cellulose were sulfonated and cross-linked. The membranes were prepared by sol-gel casting method with different amount of cross-linking reagent. In conclusion, the composite membranes I, II, III showed improved thermostability, tensile strength and oxidative durability. Proton conductivity of the membranes was also improved and the composite membrane I showed 0.1312 S/cm at $80^{\circ}C$ which was the best of those composite membranes.
