Dielectric behavior of O3-type piezoelectric composites
Dielectric properties of ferroelectric ceramic loaded P(VDF/TFE) polymer were studied in the frequency range 20 Hz to 1 GHz and at temperatures from 110 to 420 K. A simple relaxation with activation energy of 1.8 eV, observed at temperatures from 225 to 275 K and frequencies from 20 Hz to approximately 5 kHz, is related to the dielectric absorption in the amorphous phase of the polymer. At higher frequencies and temperatures complex and non-Arrhenius behavior of the main absorption of the O3-type composite is observed. Moreover, in the frequency range >
