摘要

Chondroitin sulfate C (CSC), one of the natural polysaccharides, is present in the connective tissue,brain, and cartilage. Therefore, the utilization of CSC has been limited to biological materials. In thisstudy, we applied the CSC to the engineering field as a proton conducting material. The anhydrousproton conductive CSC-heterocycle composites were prepared by mixing the CSC material and theheterocycle imidazole (Im). The CSC-Im composite formed an acid-base composite by the electrostaticinteraction between the acidic group, such as the carboxyl and sulfonic acid groups, and the nonprotonated –N= of the Im molecule and showed a thermal stability at < 200 °C. Additionally, theanhydrous proton conductivity of the CSC-Im composite increased with the addition of the Immolecule and indicated the maximum value of 1.1 ? 10-3 S cm-1 at 130 °C under flowing dry-nitrogen.Furthermore, the activation energy (Ea) of the proton conduction was 0.3 – 0.4 eV and this Ea valuecoincided with that of other anhydrous proton conductors. Therefore, the CSC-Im composite might beused as a novel anhydrous proton conductor.
