Abstract : The first and second reports (combined) showed that the composite films of PZT/PVDF, prepared in our laboratories, may have a permittivity in excess of 100 for a 75% volume fraction of PZT powder introduced in the matrix of PVDF host polymer. The relative permittivity of the ceramic polymer composites were measured in the frequency range of 10Hz-65kHz and compared with the respective permittivity values of PZT and PVDF. It was also observed that the dielectric relaxation of this PZT/PVDF composite conforms with that of the polymer (PVDF). Present work extends above work to investigate the dielectric loss behaviour of the composite.
