Facile synthesis of polyaniline-nickel oxide composites via interfacial polymerization

Nowadays, devices for storing electrical energy which are batteries and capacitors are widely used in electrical industries. The researchers are currently interested in studying and developing the capacitors to be more capacitance and electrical energy storage. In this study, polyaniline-nickel oxide (PANINiO) composites were prepared via interfacial polymerization method. It is a facile synthesized process at room temperature and can control the morphology of materials. The objective was to study the effect of mass ratios of aniline monomer to NiO nanoparticles (1:0.5, 1:1.0, 1:1.5, 1:2.0 and 1:2.5) on the morphology and electrochemical properties. The PANI-NiO composites were investigated by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and cyclic voltammetry (CV). The FTIR, XPS and XRD results have confirmed the synthesis of the composites. SEM and EDAX results presented the NiO nanoparticles were dispersed within PANI nanofiber. The CV results indicated that the higher NiO content, the specific capacitance increased.Copyright (c) 2021 Elsevier Ltd.
