Dielectric Properties and Relaxation Processes in Nanocomposites Based on Polylactic Acid and Carbon Nanotubes

Abstract

The dielectric properties of nanocomposites based on polylactic acid with the addition of carbon nanotubes, as well as relaxation processes in them, have been studied. The dependence of the dielectric permittivity on the frequency and the filler concentration is found, the percolation threshold is determined, and the relaxation behavior of the system is analyzed using the electric modulus. The results obtained testify to the influence of the structural and interfacial effects on the dielectric characteristics of the composite, which is important for the development of new functional materials.
