摘要
本文采用超声波法制备了Sn_(0.95)Mg_(0.05)P_2O_7-聚甲基丙烯酸甲酯(PMMA)新型有机-无机固体离子复合电解质、运用X射线衍射、扫描电子显微镜和红外光谱仪对样品进行了表证,并且测定了电导率随温度的变化规律.XRD、红外测试表明Sn_(0.95)Mg_(0.05)P_2O_7和PMMA混合没有发生反应生成新物质;SEM表明样品的致密良好.电导率测试表明温度为140℃时电导率达到最大值0.
The new organic- inorganic ionic solid composite electrolyte Sn0. 95Mg0. 05P2O7- PMMA was prepared using an ultrasonic method. The electrolyte was characterized by using infrared spectrometer,SEM and XRD. For the electrochemical determinations,the conductivity was measured by an AC impedance method. XRD and IR show that there are only peaks corresponding well to Sn0. 95Mg0. 05P2O7 and PMMA,without any formation of other substances. SEM shows that the density of the sample is good. The highest conductivity is observed in unhumidified air to be 0. 05 S·cm- 1at 140 °C.
