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.
