INVESTIGATION OF BZT BASED PVDF POLYMER MATERIALS: MICROCRYSTALLINE, MORPHOLOGICAL AND ITS ELECTRICAL BEHAVIOUR STUDY

Abstract: Since from many decades man is being using natural resources in many ways in this society, he has also conserved energy, which has made him too led comfort life. Advancement of conductive polymers heavily relies on the study of various piezoelectric rich polymer energy sources and their features since these materials are the easiest to come by in nature, affordable, environmentally acceptable, and have strong electrical potency. In the present research work Barium Zirconate Titanate (BZT) is a piezoelectric enhanced material and its performance is studied. By using the hydrothermal approach and the Co-precipitate gel technique, BZT nano materials were effectively synthesized and studied the electrical behavior performances. The BZT nano composite synthesized, exhibited Ba (Zr0.25Ti0.75) O3) phase was added polyvinylidene fluoride (PVDF) polymer matrix which was prepared by simple solvent casting process. The XRD and SEM have revealed purity phase and formation of BZT nano particles have composited along with α and β-phase PVDF polymer. The prime electrical properties such as dielectric conductivity, dielectric loss, and dielectric constant parameters of Barium Zirconate Titanate (BZT)-polyvinylidene fluoride (PVDF) were evaluated and further analyzed in detail with consideration of different frequencies in dielectric studies. Maximum dielectric loss with regard to frequency was observed in 0.5%BZT-PVDF films, which have witnessed for high dielectric stability, and the conductivity was raised with 0.5%BZT based PVDF polymer films as compared to pure PVDF polymer. Our experimental studies demonstrate the strong frequency dependence of dielectric parameters including real and imaginary modulus as well as dielectric loss. Additionally, the investigation has provided convincing evidence for the pure PVDF polymer film's melting point and dynamic mechanical analysis (DMA), which helps us understand the stability of conductive polymers
