▎ 摘　　要

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.
