Highly Transparent Piezoelectric PVDF Electrospun Membranes

Abstract

In this work, electrospun membrane with excellent optical transparency has been developed and the study focuses on the optical and electromechanical properties of the membrane. Highly transparent PVDF based membrane fabricated by electrospinning exhibited appreciable piezoelectric property. Thus the study mainly focus on the multifunctional behaviour of these nanomembrane in the field of transparent sensors and energy harvesting systems. The transmittance of the fabricated membrane is measured using spectrophotometer and beta sheets content associated with the piezo activity of the membrane is measured using the Fourier Transform Infrared spectra. The surface characterization of the electrospun membrane were performed using Scanning Electron Microscope (SEM). The piezo response range of these membrane were tested using impulse loading and force voltage-based measurements. The utilization of these transparent optical membranes in the field of micro and nanoenergy harvesting systems based on piezoelectric transduction mechanism is focused.
