The nature of absorption and steady state electrical conduction as well as the dielectric and pyroelectric behaviour have been studied for polymer/ceramic composites. Experimentally observed values of pyroelectric coefficient and dielectric permittivity for various PZT content of PZT/PVDF composites seem to agree well with the calculated values. A high dielectric permittivity of polymer coupled with high pyroelectric activity of PZT may contribute to the high pyroelectric coefficient in the PZT/PVDF composites. The dielectric loss processes of the polymer-ceramic composites are observed to be dominated by those of the polymer whereas the ceramic phase may contribute significantly to the steady state electrical conduction which is suggested to be of ionic origin.
