In this paper is illustrate the dielectric characteristics of a nanocomposite polymer matrix based on polypropylene (PP) with insertion of multi-walled carbon nanotubes (MWCNTs). The dielectric characteristics analyzed are the real and imaginary part of permittivity, dielectric losses and electrical conductivity of the sample based on PP with 5% insertion of MWCNTs. The measurements are done in a range of frequency between 1 MHz to 3 GHz and for a variation of temperature from 30°C to 120 °C, with a step of 5°C. Graphical representation of dielectric characteristics are done in 2D and 3D plans.
