Investigation of structural, dielectric and sensing properties of MgCl₂/PVDF composite films prepared via solution casting technique

Abstract

This article investigates the effect of Mg insertion into the Polyvinylidene fluoride (PVDF). The composite films were prepared using solution casting technique. XRD, and FTIR characterizations were done to study the structural changes in the MgCl2/PVDF composite films. The dielectric study reveals the improvement in the dielectric constant and conductivity with the insertion of Mg ions in the PVDF composite. The MgCl2/PVDF composite has immense potential in sensing and actuator applications.
