To investigate the conduction properties of ionic liquid crystal electrolytes and to correlate them to their molecular structure, two electrolytes based on imidazolium iodides have been chosen for a comparative study: one ionic liquid crystal (1-dodecyl-3-methylimidazolium iodide) (C12) and one ionic liquid (1-hexyl-3-methylimidazolium iodide) (C6). For the electrical characterization of the samples the electrochemical impedance spectroscopy technique (EIS) has been used in the frequency range 1 MHz ÷ 10 mHz. For both electrolytes three frequency domains have been singled out. At large frequencies a hopping mechanism ensures the relative high conductivity of ionic liquids. A good fit of the conductivity data with respect to temperature with a Vogel-Tamman-Fulcher (VTF) equation has been done. The interesting result is that although C12 has a higher viscosity than C6 and thus a smaller conductivity was expected the observed conductivity is actually larger, this fact being attributed to the smectic A liquid crystal order of C12. At medium frequencies and especially at low frequencies the buildup of double layers by the electrodes is well observed. Assuming that in this region (10 Hz ÷ 10 mHz) the cell is equivalent to an electric circuit formed by the parallel of a resistance, R₀, and a capacitance, C₀, the simple Debye relaxation model, characterized by one relaxation time, has been modified taking into account the adsorption phenomenon in the Langmuir approximation. A theoretical interpretation of the experimental results based on the double layer model is presented.

为了研究离子液晶电解质的导电特性并将其与分子结构相关联，已选择了两种基于碘化咪唑的电解质进行比较研究：一种离子液晶（1-十二烷基-3-甲基咪唑碘化物）（C12）一种离子液体（1-己基-3-甲基咪唑碘化物）（C6）。为了对样品进行电学表征，已在1 MHz÷10 mHz的频率范围内使用了电化学阻抗谱技术（EIS）。对于两种电解质，已经选出了三个频域。在较大的频率下，跳变机制可确保离子液体的相对较高的电导率。用Vogel-Tamman-Fulcher（VTF）方程已很好地拟合了电导率数据相对于温度的关系。有趣的结果是，尽管C12的粘度比C6高，因此预期电导率较小，但观察到的电导率实际上更大，这是由于C12的近晶A液晶级。在中频下，尤其是在低频下，可以很好地观察到电极形成的双层。假设在该区域（10 Hz÷10 mHz）中，该单元等效于由电阻的并联形成的电路，考虑到Langmuir近似中的吸附现象，对R ₀和电容C ₀（以一个弛豫时间为特征的简单Debye弛豫模型）进行了修改。提出了基于双层模型的实验结果的理论解释。
