Year: 2024
Type: article
Abstract: We report the preparation of polyaniline (PANI) covered La2O3 binary composite material using in situ oxidativepolymerization method using APS as oxidant in acidic medium.Prepared material was characterized using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) to understand the structure and bonding.Transmission electron microscopy (TEM) estimated the particle size confirming the synthesis of particles in nanorange.For chemical composition and thermal stability, energy dispersive X-ray and thermogravimetric (TG) analysis respectively were performed.Cyclic voltametric measurement of PANI-La2O3 nanocomposite having a semi-rectangular loop of high area exhibited high specific conductance (Csp = 373 Fg-1).The high ionic and electrical conductivity alongwith high charge storage capability makes PANI-La2O3 nanocomposite a potential candidate for its usage as electrode material in supercapacitor.
