| Research Abstract |
We used a supercritical carbon dioxide (scCO_2) treatment technique for improvement in ionic conductivity and dispersion of solid polymer electrolytes (SPE)-clay composites. In this study, we prepared amorphous polyether/saponite (S_<Na>) composites treated with the scCO_2 and characterized the properties. Wide-angle X-ray diffraction (WAXD) patterns of the composite samples indicated almost no expansion of the d-spacing with the scCO_2 treatment. However, the conductivity of the scCO_2-treated samples was higher than that of the original samples. In particular, the scCO_2-treated sample including 10wt% of freeze-dried S_<Na> showed approximately 35-times higher conductivity than the original sample at 30℃.
