摘要
采用原位聚合制备出新型的BM IPF6/PMMA聚合物电解质透明弹性膜.研究结果表明,BM IPF6/PMMA聚合物电解质体系在305℃时仍具有较好的热稳定性,其安全性能优于含有机溶剂的传统非水电解质体系.随着离子液体含量的增加,其玻璃化转变温度逐渐减小,离子电导率升高;且离子电导率与温度的关系服从VTF方程.其中,当BM IPF6的质量分数为50%时,该聚合物电解质的室温离子电导率高达0.15 mS/cm.
In order to achieve highly conductive polymer electrolytes, a room-temperature ionic liquid BMIPF6 was prepared, and the ionic liquid-polymer electrolytes were prepared by the in situ polymerization of MMA in ionic liquid BMIPF6. DSC analysis and ac impedance measurement revealed that ionic liquid BMIPF6 could reduce glass transition temperatures, and increase ionic conductivity of the composite ionic liquid-polymer electrolytes. And the activation energies of ions were calculated according to VTF equation. The composite polymer electrolyte plasticized with BMIPF6 （50%） exhibited an excellent ionic conductivity up to 0. 15 mS/cm. In addition, one of the main advantages of the system was the non-volatility of the components, which had higher decomposition temperatures and was safer than the traditional non-aqueous electrolyte systems including organic solvent.
