Molecular mobility in piezoelectric hybrid nanocomposites with 0–3 connectivity: Volume fraction influence
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.
