Abstract

Composite materials from polyvinylidene fluoride and ceramics barium titanate (PVDF/BaTiO₃) have been prepared. Polymer/ceramic films composites with 0-3 connectivity pattern have been produced by introducing fine grain BaTiO₃ powder in the matrix of PVDF using a well- known hot-pressure method. The addition of the ceramic powder to the polymer modifies in wide range both the dielectric and the mechanical parameters which determine the piezoelectricity of the materials. These films were polarized by the conventional technique. The results of measurements of the piezoelectric parameters and the dielectric properties of the PVDF/BaTiO₃ mixture with the various volume fraction of the components are given in this report.
