采用微波合成法制备了室温离子液体3-乙基-1-甲基咪唑鎓四氟硼酸盐(EMIBF4),通过元素分析和FTIR光谱对其进行了表征. 将其作为偏氟乙烯-六氟丙烯共聚物(P(VDF-HFP))基聚合物电解质的增塑剂,制备出弹性聚合物电解质膜. 热失重分析显示EMIBF4可明显增强聚合物电解质的热稳定性. 循环伏安法研究此种聚合物电解质膜对不同金属集流体(Ni,Al,Cu)的电化学稳定性. 通过交流阻抗测试探讨了聚合物电解质(0.5 g P(VDF-HFP)/0.5 g EMIBF4/0.01 g LiBF4)的离子电导率,根据Arrhenius公式计算出该体系的离子输运活化能为7.27 kJ/mol.
