【 摘 要 】

The aim of this work is an experimental study of the dielectric properties of nanocomposites with a matrix of silica reinforced with multi-walled CNTs at different concentrations and to determine the role of the CNT in the scattering and absorption of electromagnetic radiation in the range of extra-long and medium radio waves (25 Hz-1 MHz). The study found that in addition to the standard behavior of the electrical characteristics of nanocomposites with increasing concentration there was an optimum concentration of carbon nanotubes at which conductivity and absorption of electromagnetic radiation in the material greatly increased. This can be used to enhance the functionality of nanocomposites.
