Thermal Polarization Mechanisms of O-3 Type Ferroelectric Composites

Huang Xue, Jing Li

Abstract

The O-3 type composites of TGS, BaTiO3, PZT and LiNbO3 based on PVDF were prepared.The long term polarization relaxation in these composites was studied. It indicates that there arethree mechanisms with different relaxation time. These mechanisms result from crystalline grainsof the crystal or ceramics, matrix and grain boundaries. A stable polarization results from thegrain boundaries.
