摘　　要：合成了聚氧化乙烯聚氨酯 (PEU)和一种新型的单离子磺化聚醚硫酸盐 (SPEO) ,将 SPEO与 PEU共混得到单离子型聚合物固体电解质 .利用红外光谱、拉曼光谱、元素分析、复阻抗谱分析等对样品进行了表征 .结果表明 ,磺化聚醚硫酸盐和聚氨酯体系的电导率较高 ,中等温度 (3 8℃ )下其电导率 σ达到 2 .5×1 0 - 6 S/cm,是一种性能优良的单离子固体电解质体系 .The sulfonated poly(ethylene oxide)sulphate/polyurethane mixture was prepared from polyethylene oxide, 1,4-butanediol and methylene-bis(4-phenyl isocyanate). The samples were characterized by FT-IR and elemental analysis. The ionic conductivity was calculated based on the impedance measurements. The relation of the conductivity with ion concentration, sulfonated polyether content and temperature were discussed. The conductivity of 2 5×10 -6 S/cm for the polymer electrolyte was obtained at room temperature.
