The temperature dependence of the ionic conductivity is studied in a series of poly(propylene glycol) diacrylate monomers. The experimental data are analyzed by means of the approach recently proposed by Petrowsky et al. [J. Phys. Chem. B. 113, 5996 (2009)10.1021/jp810095g]. This so-called compensated Arrhenius formalism (CAF) approach takes into account the influence of the dielectric permittivity on the exponential prefactor in the classical Arrhenius equation. The experimental data presented in this paper show a good agreement with the CAF; this means that the exponential prefactor is principally dielectric permittivity dependent. The compensated data revealed two conduction processes with different activation energies; they correspond to low and high temperature ranges, respectively.
在一系列聚丙二醇二丙烯酸酯单体中研究了离子电导率的温度依赖性。实验数据通过Petrowsky等人最近提出的方法进行分析[《物理化学杂志B》113, 5996 (2009)10.1021/jp810095g]。这种所谓的补偿阿仑尼乌斯形式（CAF）方法考虑了介电常数对经典阿仑尼乌斯方程中指数前因子的影响。本文给出的实验数据与CAF吻合良好；这意味着指数前因子主要取决于介电常数。补偿后的数据揭示了两个具有不同活化能的传导过程；它们分别对应于低温范围和高温范围。
