Synthesis and characterization of flexible films of PVDF/ Pb(Fe0.585Nb0.25W0.165)O3 polymer multiferroic composites

Abstract

The films of Poly(Vinylidene Fluoride)/Pb(Fe0.585Nb0.25W0.165)O3(PVDF/PFNW) polymermultiferroic composites were prepared using standard solution casting method. The room temperature XRD confirms the presence of different phases of PVDF matrix and the PFNW filler perovskite phase of the incorporated ceramics.The morphology studies show the surface appearance of the films with agglomerative nature. The dielectric constant and loss tangent of PVDF/PFNWshow the frequency dependent nature. The dielectric constant and loss tangent was increasedwith increasing the weight percent of PFNW particles in the PVDF matrixshowing the evidence of strong dependence on PFNW substitution into the PVDF matrix. Real part of the impedance and modulus decreased with increasing PFNW concentration indicates the increase ofconductivity inthe composite.
