Energy Harvesting from Lead-free Piezoelectric materials.

Abstract

Barium calcium zirconate titanate (Ba0.85Ca0.15Ti 0.9Zr0.1O3, BCZT) ceramic have been successfully synthesised by sol-gel method. The synthesized powder is calcined at 1000 ℃ for 3hr, to obtain the single-phase perovskite structure. The flexible nanocomposite films of BCZT/ Polyvinylidene fluoride (PVDF) has been fabricated by solution casting method. The microstructure and the morphology have been studied by SEM. The particle is homogenously dispersed in the PVDF matrix as confirmed by SEM. Formation of the phase and crystallite size is obtained by the X-ray diffraction. The average crystallite size obtained is ~ 26nm.
