Impedance spectroscopy of high-molecular poly(ethylene) with carbon nanotubes

The impedance spectra of composite materials based on the high-molecular poly(ethylene) modified by carbon nanotubes have been investigated. A numerical method has been proposed for reconstructing the relaxation time distribution function of the active $(R)$ and reactive $(C)$ elements of a sample directly from the experimentally obtained frequency dependence of the real and imaginary components of the impedance. It has been shown that, with an increase in the concentration of carbon nanotubes, the electrical conductivity of the samples under study increases and their impedance characteristics are described by a nonmonotonic relaxation time distribution function.
