Synthesis and characterization of ferroelectric polymer ceramic composites

Kar, M (2014) Synthesis and characterization of ferroelectric polymer ceramic composites. MSc thesis.



Ferroelectric polymer-ceramic composites were prepared by the solution casing technique usingpolyvinylidenefluoride (PVDF) as polymer matrix and Na0.5Bi0.5TiO3 (NBT) as the ceramic powder. The concentration of NBT has been varied with respect to polymer host. The formation polymer composites have been confirmed by the X-ray Diffraction (XRD) analysis. The presence of both the crystalline and amorphous phases has also been observed from XRD pattern. Fourier transform infrared spectroscopy (FTIR) confirms the presence of vibrational bands of both the phases in the composite. The microstructure/surface morphology of the polymer-ceramic composites was analysed by the optical microscopy.Dielectric properties of the composites have been studied with the variation of frequency at room temperature.
