Effect of Adding BaTiO3 to PVDF as Nano Generator

Piezoelectric nanogenerator based on a composite structure formed of Polyvinylidene Fluoride (PVDF) as the matrix and Barium Titanate BaTiO₃ nanospherical after dissolving them in a solvent of Dimethyl Sulfoxide DMSO/Acetone in (1/3 v/v) then spanning it's homogeneous solution on Aluminum foil. structural and morphology analyses that of fabricated nanofibers characterized by X-ray diffraction, Scanning Electron Microscope and the electrical output of piezoelectric membrane devices was measured by using oscilloscope. The electrical output of different samples were measured for the pure powder PVDF and for composite PVDF& BaTiO₃. The highest PVDF composite piezoelectrically generated voltage for samples with BaTiO₃ (20%PVDF & 25% BT) wt. %. where improved to 6 V in general the addition of BT Nc increases the piezoelectric response of electrospun PVDFnanofibers.
