摘　　要：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 novel polymer electrolyte system based on polyurethane/sodium sulphonate-sidechain-grafted poly(ethylene oxide) (SPEO) blends was studied. The blends with different relative molecular mass were synthesized on the basis of sulfonation and esterfication between dimethyl fumarate (DMF) and poly(ethylene oxide). Results showed that the mobility of ion and polymer chain segments increased with increase in relative molecular mass of SPEO.
