摘要:

我们探索了一个理想化的理论模型,在高度不对称的离子液体混合物中的离子传输。原始模型(PM)启发的系统用作不对称离子材料(例如液晶盐)的代表,其猝灭以形成无序的部分停滞相。应用自洽广义朗之万方程(SCGLE)理论研究了电荷匹配盐的粒径比与平均迁移率之间的关系。在这个模型中,我们确定新的玻璃态,其中两个带电物种(无论是大阳离子或微阴离子)被逮捕,而其他保留流动性。我们讨论了如何这一结果是有用的,在离子液体为基础的材料中的新型单离子导电相的发展。

英文摘要:

We explore an idealized theoretical model for the transport of ions within highly asymmetric ionic liquid mixtures. A primitive model (PM)-inspired system serves as a representative for asymmetric ionic materials (such as liquid crystalline salts) which quench to form disordered, partially-arrested phases. Self-Consistent Generalized Langevin Equation (SCGLE) Theory is applied to understand the connection between the size ratio of charge-matched salts and their average mobility. Within this model, we identify novel glassy states where one of the two charged species (either the macro-cation or the micro-anion) are arrested, while the other retains mobility. We discuss how this result is useful in the development of novel single-ion conducting phases in ionic liquid based materials.
