Abstract

The present paper is presenting a study regarding the dielectric behavior of a polymeric matrix based on polypropylene (PP) reinforced with 5% wt of multi-walled carbon nanotubes (MWCNTs). A complex qualitative and quantitative analysis of real and imaginary permittivity evolution as function of frequency and temperature allowing the understanding of polarization mechanisms. The dielectric measurement were performed via Broadband Dielectric Spectrometer in a wide range of frequency, from 10 Hz up to 10 Mhz, and at temperatures between 30°C to 120°C.
