Effect of Oxidizer on PANI for Producing BaTiO3@PANI Perovskite Composites and Their Electrical and Electrochemical Properties

Abstract Polyaniline (PANI) has received significant attention in basic and applied studies because it electrical electrochemical properties comparable to conventional semiconductors metals. PANI's can be controlled through its preparation methods. Accordingly, the present work, two different samples of PANI were prepared by polymerization aniline monomer via situ method using oxidizers dichromate (PANI (1)) persulphate (2)). The products blended with BaTiO 3 (BTO) form BTO@PANI composites. composites characterized scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), photoelectron (XPS). SEM illustrated covering layers on BTO nanoparticles. studied. BTO@PANI(2) composite sample showed a conductivity 1.2 × 10 –3 S/cm higher than that found for each BTO@PANI(1) 9.1 –4 constituents. supercapacity capacity values 70 F/g, 76 F/g BTO@PANI(1), BTO@PANI(2), respectively, which are
