Ferroelectric Studies On Poly (Vinylidene Fluoride)/NiFe2O4 Polymer Nanocomposite Structures.

Polyvinylidene Fluoride (PVDF) based nano composite structures are prepared by using nanosized NiFe2O4 as filler at different concentrations. The structural and morphological studies made with the help of X-ray Diffractometer and Transmission Electron microscope are presented in this paper. The Ferroelectric property exhibited by the unpoled polymer and composite samples at different temperatures are reported. The dependence of polarization on the filler concentration and temperature are also discussed. [ABSTRACT FROM AUTHOR]
