Abstract
Abstract : Composites of Lead Zirconate Titanate(PZT)and polyvinylidene fluoride(PVDF)were prepared and its electrical and dielectric behaviours were analysed. PZT phase has been suggested to have a significant contribution on the electrical conduction and low frequency dielectric loss at high temperatures. The pyroelectric behaviour obtained from composites of different materials may suggest that the elastic stiffness and thermal expansion of the polymer matrix were among the factors contributing to the measured pyroelectric activity. A higher pyroelectric figure of merit as compared to PZT has been achieved in one of the PZT/PVDF composites. Keywords: Steady state; Composite materials; Phase studies; Foreign technology. (jes)
