Piezoelectric Polymer/Ceramic Composite

Abstract

Composite films of lead zirconate titanate (PZT)/poly vinylidene fluoride (PVDF), PZT/Copolymer of vinylidene fluoride - trifluorethylene (VDF- TrFE) and Barium titanate (BaTiO3)/PVDF were prepared in our laboratories and their electrical, dielectric and pyroelectric properties were investigated. PZT phase appears to provide a significant contribution to the electrical conductivity of these composites whereas the dielectric dispersion is influenced by the polymer and copolymer phase. The composite film of PZT/VDF-TrFE appears to be an attractive electro-active material with a pyroelectric coefficient an order of magnitude greater than that of PVDF whereas its figure of merit is significantly higher than that of PZT.
