摘要
以单阳离子导体作为传导模型,通过对阳离子淌度的表征,证实了碱金属盐在聚合物介质中的负温度依赖性。发现在离子传导过程中,离子淌度对其电导率温度依赖性的影响远甚于载流离子数。并运用聚合物链段松驰理论对这种反常离解行为进行了唯象学的诠释。
The negative temperature dependence of alkali salt dissociation in polyether media was studied with the aid of ionic conductivity and mobility of polymer single-ion eonduetors. It was found that thetransport process of carrier ions is predominated by their mobility rather than their numbers. The phenomenon was explained by the theory of polymeric segmental relaxation.
