Effect of Adding BaTiO3 to PVDF as Nano Generator

Abstract

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.

High-Performance Flexible Piezoelectric Nanogenerator Based on Electrospun PVDF-BaTiO3 Nanofibers for Self-Powered Vibration Sensing Applications

“…Primarily, the technique used in our synthesis was electrospinning, which enables in situ poling and is relatively easier for the formation of the β-phase with the highest fraction. Compared to this, PVDF-BT composites synthesized via solvent casting and nanoimprinting processes could generate a higher voltage only when it is subjected to high pressure. , Among ES PVDF-BT composites in the table, − our device could achieve a higher voltage of ∼50 V from a small PENG device by applying a meager force of ∼3 N, which is the lowest considering the quantum of voltage generated. This promising result stems from the proper optimization of electrospinning parameters, which makes the fraction of the β-phase higher , and also facilitates the meticulous design of the device.…”

A Review of Piezoelectric PVDF Film by Electrospinning and Its Applications

“…The amount of BT was between 0.4 and 0.8 wt.%. On the other hand, a DMSO/acetone solvent mixture was used with a higher BT (20 and 25%) powder to prepare a PVDF film by Hussein et al [ 102 ]. This work demonstrated that the addition of BT to the electrospinning process of PVDF promoted β-phase crystallization over α-phase.…”

“…The formation of desired β-phase PVDF was shown with a sample of 3 wt.% BT addition. Moreover, the capacitance increased significantly for BT/PVDF samples compared to pure PVDF [ 102 ].…”

Flexible Piezoelectric Pressure Tactile Sensor Based on Electrospun BaTiO3/Poly(vinylidene fluoride) Nanocomposite Membrane

“…11 As piezoelectric nanocomposites obtained via electrospinning provide a large piezoelectric coefficient and excellent flexibility, flexible piezoelectric pressure sensors based on PVDF nanocomposites obtained from electrospinning have a great potential for the wearable devices by achieving the efficient conversion between mechanical energy and electrical energy. Recently, Hussein et al 17 fabricated a piezoelectric nanogenerator based on a composite structure formed of PVDF as the matrix and BaTiO 3 nanospheres. Yaqoob et al 18 used a method of spray coating to prepare a trilayer flexible piezoelectric nanogenerator based on surface-modified graphene and PVDF-BaTiO 3 nanocomposites.…”
