Transport properties of polymeric electrolytes studied through electric and mechanical relaxations

在同一频率范围内测量了锂盐在纯净的聚合物液体中的溶液和聚合物在有机溶剂中的溶液的频率相关剪切粘度和电导率，并将前者得到的聚合物的运动与后者观察到的离子的平移运动进行了比较。在两种溶液中均未观察到剪切粘度与电导率的频率依赖性之间的对应关系，这表明稳态剪切粘度与直流离子电导率之间存在解耦。

The measurements of frequency-dependent shear viscosity and electric conductivity were performed in the same frequency region on the solution of a lithium salt in a neat polymeric liquid and polymer solutions in an organic solvent, and the motions of polymers obtained from the former were compared with the translational motion of ions observed in the latter. The correspondence between the frequency dependence of the shear viscosity and electric conductivity was not observed in both solutions, which suggests the decoupling between the steady-state shear viscosity and DC ionic conductivity.
