Poling Effect and Temperature on Electrical Behaviour of PZT-Polymer Composites with 0-3 Connectivity

V Annamalai;P Gowdhaman, R Sakthi Sudar Saravanan and Haresh M Pandya


An attempt has been made to prepare PZT-polymer composite using Poly (methyl methacrylate) and a mixed polymer (Polyvinylidene fluoride and Polyvinyl chloride) as polymer phase. Based on the properties of polymer phases, two different preparation techniques have been used for the composite preparation and a hot press method has been adopted for the sample preparation. The inhomogeneity of ceramic phase over the polymer matrix has been revealed from the surface morphological studies. Dielectric constant and dielectric loss of the composite is found to be increased with the increase in temperature irrespective of poled and unpoled samples. Temperature dependence of AC conductivity increases with rise in temperature. The dielectric and pyroelectric performance of PZT-PMMA composite lags behind the PZT-PVDF/PVC composite.
