摘要:
以甲氧基聚乙二醇甲基丙烯酸酯(MPEGM)和十六烷基聚乙二醇甲基丙烯酸酯(HPEGM)为单体,采用自由基溶液聚合法制备无规接枝共聚物P(MPEGM-HPEGM),并以此共聚物为基体混合锂盐(LiClO4)制备全固态聚合物电解质。用红外光谱(FT-IR)、差热分析(DSC)和交流阻抗(EIS)等方法对聚合物和聚合物电解质的性能进行研究。结果表明:MPEGM和HPEGM共聚生成P(MPEGM-HPEGM); 聚合物中聚氧化乙烯(PEO)链段的运动能力得到提高,有利于离子传输; 聚合物电解质膜的电化学稳定性窗口达到4.5 V; 在30 ℃时,当MPEGM与HPEGM的质量比为80:20,锂盐与氧化乙烯(EO)的摩尔比为1:20时,聚合物电解质的离子电导率达到最高7.6×10-5 S/cm; 离子电导率随着温度的升高而迅速增加,电导率-温度的关系符合VTF方程。
Abstract:
A novel graft copolymer P(MPEGM-HPEGM)was prepared by co-polymerizing of two macro-monomers:methoxy-poly(ethylene glycol)methacrylate(MPEGM)and hexadecal-poly(ethylene glycol)methacrylate(HPEGM).And the polymer electrolytes were prepared by blending P(MPEGM-HPEGM)and LiClO4.The performances of the polymer and polymer electrolytes were studied by Fourier transform infrared spectrometry(FT-IR),differential scanning calorimetry(DSC)and electrochemical impedance spectroscopy(EIS).The results showed that P(MPEGM-HPEGM)was successfully synthesized and the motion of poly(ethylene oxide)(PEO)chains was improved.The electrochemical stability of the polymer electrolytes was up to 4.5 V.When the weight ratio of MPEGM to HPEGM was 80:20 and the mole ratio of lithium salt to ethylene oxide(EO)was 1:20,the maximum ionic conductivity reached 7.6×10-5 S/cm at 30 ℃.The temperature dependence of ionic conductivity of solid polymer electrolytes appeared to obey Vogel-Tamma-Fuleher(VTF)equation.
