A complete examine of the correlation between the structural and morphological parameters and the frequency-temperature dependences of the conductivity of porous carbon supplies obtained by carbonization of hemp fibers has been carried out. The impact of therapy with nitric acid and extra annealing on the transport of cost carriers in carbon supplies carbonized within the temperature vary of 500–1000 °C has been established. Porous carbon supplies have been described as a heterophase system, through which extremely conductive graphitized particles are separated by low conductivity amorphous carbon, from the standpoint of the impact of carbonization temperature and adjustments within the morphology of supplies because of acid therapy and annealing on the formation of conduction channels with the simultaneous implementation of fluctuation-assisted tunneling between graphitic clusters separated by low conductive limitations and the formation of conduction channels on account of contact of particular person graphitized carbon clusters. A mannequin has been constructed that relates the outcomes of measuring the particular floor space and pore dimension distribution, adjustments within the dimension of graphite crystallites, and adjustments in conductivity with temperature. The opportunity of making use of the speculation of percolation conductivity to explain the cost transport has been analyzed and the percolation threshold has been established.
