Abstract

A phenomenon of change in the frequency of a mechanically activated current was detected for the first time. This phenomenon consists in the fact that electric current pulses produced by a rheological explosion differ in frequency characteristics between a polypropylene‑graphene nanoplates composite and the matrix polymer (polypropylene). It was shown that the Fourier transforms of the current signals from the composite according to the Havriliak–Negami model for the experimental frequency dependence of conductivity agree well with the results of the calculation using the Drude model for multilayer graphene.

脉冲机械作用下聚丙烯-石墨烯纳米板复合材料的高频电子输运

首次发现了机械激活电流频率变化的现象。这种现象是由于流变爆炸产生的电流脉冲在聚丙烯-石墨烯纳米板复合材料和基体聚合物(聚丙烯)之间的频率特性不同。结果表明，基于Havriliak-Negami模型的电流信号的傅里叶变换与基于Drude模型的多层石墨烯的计算结果吻合得很好。

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
