Abstract. This study presents a comparison of dielectric properties of composite materials consisting of insulating polymers (Polyamides 6 and 12) containing polyaniline (PANI) as a conductive phase. Samples were obtained by in situ polymerization of the aniline monomer in presence of the insulating matrices. The results obtained by dielectric relaxation spectroscopy showed that it was possible to increase the permittivity of the samples by increasing PANI content. The PANI also induces relaxation phenomena, clearly visible at low temperature. These relaxations seem to be of the same nature in polyamides (PA12 and PA6) films because appearing at nearly the same frequency. It was also shown that dielectric relaxation phenomena are thermally activated.
