【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.更多还原

【Abstract】 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.更多还原
