Abstract
Thermo Stimulated Current and Dynamic Dielectric Spectroscopy studies were carried out on hybrid ferroelectric Polyamide 11/Barium Titanate to investigate dielectric relaxation modes. 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 molecular mobility associated with the liquid dynamic is not influenced by the volume fraction. The evolution of low frequency 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.
