Abstract

Background: The paper describes the types and electrical properties of polymer nanocomposites containing carbon allotropes.

Objective: Direct current conductivity, conduction in percolation systems, conduction mechanisms and factors controlling conductivity and percolation parameters are considered.

Method: The dielectric properties of polymer nanocomposites are presented, and experimental methods and methods for analyzing the results have also been described. An analysis of the data on ac electrical conductivity, including the contribution of nanofiller - interfacial polarization is presented. Special consideration is given to the role of nanocarbons as dielectric probes.

Results: The microwave properties of polymer nanocomposites, their use to estimate the distribution of nanofiller in the matrix, as well as practical applications for shielding and absorption of electromagnetic radiation have been analyzed.

Conclusion: The use of carbon allotropes nanoparticles as fillers with high electrical conductivity provides polymer composites with useful electrical properties, including the ability to absorb highfrequency electromagnetic radiation.

Keywords: Dielectric properties, electrical conductivity, fillers, nanocarbon, nanocomposites, polymer composites.
