Abstract

ThermoStimulated Current and Dynamic Dielectric Spectroscopy studieswere carried out on hybrid ferroelectric Polyamide 11/Barium Titanate to investigate dielectric relaxationmodes. The correlated results obtained by both methods allow us to describe precisely the molecular mobility of this 0–3 nanocomposite; in this work we will focus on the influence of the 700 nm nanoparticles volume fraction. The dielectric spectroscopy shows that the molecularmobility associatedwith the liquid dynamic is not influenced by the volume fraction. The evolution of lowfrequency relaxation, observed by depolarization currents techniques, have been attributed to the decrease of Cooperative Rearranging Region size and the increase of intra/inter macromolecular interactions in the soft amorphous phase.
