Abstract In this study, we have manufactured sensory films based on poly(3,4-ethylenedioxythiophene)/carbon nanotubes/reduced graphene oxide nanocomposite. The charge transport in obtained films was analyzed using impedance spectroscopy and temperature dependence of conductivity in the 90–325 K temperature range. The activation mechanism of charge transfer was established and the activation energy of conductivity was determined. The percolation effect in the nanocomposite was found with increasing the content of carbon nanoparticles. A decrease in resistance and an increase in the capacity of hybrid films due to the adsorption of water and ammonia molecules were revealed. Found features of the charge transport processes can expand the prospects of application of nanocomposite films for sensor electronics.

摘要 在这项研究中，我们制造了基于聚（3,4-乙撑二氧噻吩）/碳纳米管/还原氧化石墨烯纳米复合材料的感官膜。使用阻抗谱和 90-325 K 温度范围内电导率的温度依赖性分析所得薄膜中的电荷传输。建立了电荷转移的活化机制，确定了电导活化能。随着碳纳米颗粒含量的增加，发现纳米复合材料中的渗透效应。由于水和氨分子的吸附，混合膜的电阻降低和容量增加。发现电荷传输过程的特征可以扩大纳米复合薄膜在传感器电子设备中的应用前景。
