    Abstract

    The research of ehitosan modifieation with yariilin and its characterization as polymer electrolyte membranes was carried out. Chitosan-baserl sheitt base conipouatis was synthesized t'rot'n ehitosan and vanilla with pyperidine as catalyst. The polymers were eltaraelerized by Fourier Transfuritt Infrared {FTlR] and its cationic exchange capacity, while membranes were eha1'aete1'ized by cationic exchange capacity, swelling degree and its thermal stability. The existence of imine yibmtion Phalt provides that the ehitosan yaniline was sueeesfiilly synthesized. The addition of yanilliri increases the cationic exchange capasity oi‘ membrane, howeyer it tlecreases the swelling degree. Thermal data indicate the polymer rnentbraite degraded above 250°C with three step degradittion. Based on the cationic exchange capacity and its thermal stability, the membrane has a good potential for application in polymer electrolyte membrane fuel cells, but rnotlifieations are still needed to reduce the swelling degree of membrane Keyword: ehitosan, chitosan yanilin, fuel cells, polymer electrolyte ineinbraiies, sehiff base.
