Based on the statistical theory of electromagnetic processes, using the equation of balance of energy density, the features of behaviour of the polyvinylchloride (PVC) filled with micro- and nanodispersed graphite in electromagnetic field with frequency of 1–100 kHz and temperature range 298 K $\leq T \leq T_C$ + 10 K are analysed. As shown, in the range of graphite concentration 0 $\leq \varphi \leq$ 5.0 vol.%, there is a significant difference not only in the values, but also in the character of the temperature and concentration dependences of electrical conductivity of composite contained graphite synthesized by physical-chemical method and method of the chemical and electrophysical dispersion. Using the law of dissipation, both the relaxation nature and the quantitative interrelation between the electro- and thermophysical properties of investigated material are revealed.
Key words: nano- and microdisperse graphite, polyvinylchloride, fluctuations, dissipation, relaxation.
