Influence of ZrO2 and TiO2 nano particles in P(VDF-TrFE) composite for energy harvesting application

Abstract

Zirconium and Titanium material are used for making PZT piezoelectric ceramic composite. In this article, Zirconium dioxide (ZrO 2 ) and Titanium dioxide (TiO 2 ) ceramic llers with, ferroelectric polymer PolyVinyliDene uoride-Tri Fluoro Ethylene( P(VDF-TrFE)) forms the ZrO 2 /P(VDF-TrFE) and TiO 2 /P(VDF-TrFE) nano-composite. The scanning electron microscope (SEM) with EDS examine the TiO 2, ZrO 2 llers presents in composite. The ceramic llers molecules Ti 2p and Zr 3d binding energy are con rmed by X-Ray photoelectron spectroscopy (XPS). Each composite reaches their piezoelectric β-phase are con rmed by Fourier Transform -Infrared Spectroscopy (FT-IR). The low surface roughness of the thinlm reaches more exibility and deformation of cantilever. The ZrO 2 /P(VDF-TrFE) composite is obtained low average surface value of 10nm in the region of 50µm is measured from Gwyddion software. Natural resonance frequency of ceramic composite reaches 100Hz low frequency is measured by Lased Doppler Vibrometer. The cantilever beam structure energy harvester produces peak to peak output voltage 8.2 V. The harvested output voltage used for electronics devices and sensor applications.
