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

► Dielectric relaxation modes of ferroelectric Polyamide 11 / Barium Titanate nanocomposite have been studied. ► Molecular mobility is studied as function of the Barium Titanate volume fraction. ► The decrease of Cooperative Rearranging Region size and the increase of intra/inter macromolecular interactions are observed with particles content.
