PURPOSE:To enable the composition in the caption to have excellent ionic conductivity by incorporating a specific segmentalized polyetherurethaneurea and inorganic ionic salt into the composition as components. CONSTITUTION:The composition in the caption has as its components segmentalized polyetherurethaneurea including 75-95wt.% of a polyethylene oxide structure presented by a formula: (CH2-CH2O)n, and inorganic ionic salt. If the component consisting of the polyethylene oxide structure is less than 75wt.%, the ionic conductivity of the composition becomes insufficient, while if it exceeds 95wt.%, the mechanical strength of the composition deteriorates. With respect to the inorganic ionic salt, it is preferable to include, as a metallic ion, one of Li, Na, K, Cs, Ag, Cu and Mg. As a result, the composition has high ionic conductivity, excellent moldability and superior mechanical property. |
