以甲基丙烯酸甲酯(MMA)和马来酸酐(MAh)单体合成共聚物P(MMA-MAh),并以其为聚合物基体制备了凝胶聚合物电解质。采用傅里叶红外光谱(FT-IR)、差示扫描量热法(DSC)和热失重分析(TGA)对合成共聚物进行了表征,并采用交流阻抗法对制备的凝胶聚合物电解质(GPE)的导锂离子性能作了研究,并且分析了不同温度和配比对其离子电导率的影响。结果表明:成功合成了聚合物P(MMA-MAh),其热分解温度为300℃,玻璃化转变温度为133.9℃,制备的GPE的离子电导率随温度的升高而增大,随聚合物含量的增加而减小,且在研究温度范围内锂离子迁移符合Arrhenius方程。
Copolymer P (MMA-MAh) was synthesized with methyl methacrylate (MMA) and maleic anhydride (MAh) monomers, and a gel polymer electrolyte was prepared using it as a polymer matrix. The synthesized copolymers were characterized by Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The prepared polymer electrolytes GPE) lithium ion conductivity were studied, and analyzed the different temperature and the ratio of its ionic conductivity. The results showed that the polymer P (MMA-MAh) was successfully synthesized. The thermal decomposition temperature was 300 ℃ and the glass transition temperature was 133.9 ℃. The ionic conductivity of the prepared GPE increased with the increase of temperature. With the increase of temperature, Content decreases, and lithium ion migration in line with the Arrhenius equation in the study temperature range.
