| 摘 要： | 由富马酸二甲酯通过磺化及酯交换反应合成了一系列不同分子量的侧链为磺酸钠基团的磺化聚醚，并将它们与聚氨酯共混制得了阳离子型聚氨酯固体电解质，利用红外，拉曼，DSC，交流复阻抗谱对该体系进行了研究，结果表明，聚氨酯／离子化聚醚复合膜具有一定的导电能力；离子化聚醚的分子量，加入量影响复合膜的导电性能，随着离子化聚醚含量的增加，电导率增大，复合膜的导电性能随温度的上升而提高，在一定的温度范围内，导电行为符合Arrhenius公式。

| Abstract: | A series of sodium sulfonate-side chains poly(ethylene oxide)(SPEO) with different molecular weight have been synthesized based on sulfonation and esterification between dimethyl fumarate and poly(ethylene oxide). And Na + single-ionic polyurethane solid electrolytes were prepared through blending polyurethane and SPEO. Fourier transform infrared spectroscopy, Fourier transform Raman spectroscopy, DSC and complex impedance analysis were utilized to characterize structure and property of the system. It is found that PU/SPEO complex membrane exists ion conduction. Molecular weight and content of SPEO influence the ionic conductivity of complex membrane. With the increase of SPEO content and temperature, the ionic conductivity of complex membrane increases. In the range of certain temperature, ionic conductivity of PU/SPEO complex membrane follows the Arrhenius equation. |
