制备和表征了一种基于聚氨酯 /磺化低聚醚共混的单离子型固体电解质。结果表明，在一定盐浓度下，随着磺化低聚醚相对分子质量的增加，体系的相容性改善，玻璃化转变温度下降，电导率显著升高。
A single ionic solid electrolyte based on polyurethane / sulfonated oligoether blends was prepared and characterized. The results showed that at a certain salt concentration, with the increase of relative molecular mass of sulfonated oligoether, the compatibility of the system improved, the glass transition temperature decreased and the conductivity increased significantly.
