Abstract:
The measured frequency dependence of the electric impedance of a composite based on ultra-high molecular weight polyethylene reinforced with carbon nanotubes in contact with an electrolyte is presented. The behavior of the active and reactive impedance components, permittivity, and conductivity in the frequency range from 0.1 Hz to 120 MHz is analyzed. An equivalent electric circuit simulating the dispersion of the impedance of the polymer composite making contact with the electrolyte is proposed. The formation of a double electric layer at the interface between the polymer composite and electrolyte layer is demonstrated and the electrical characteristics of this layer are determined.
Keywords:
