Abstract
In the present work, polyaniline-reduced graphene oxide (PANI-rGO) nanocomposite films were synthesized by varying their concentration in composites of rGO nanosheets, and ammonium sulfate (NH4)2SO4 was used as a catalyst. The microstructural, structural network, optical, compositional, and electrochemical properties of rGO/PANI nanocomposites were investigated using scanning electron microscopy X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), UV–Vis spectroscopy, X-ray photoelectron spectroscopy (XPS), and cyclic voltammetry (CV). The XRD peaks obtained for both PANI and G/PANI Nanocomposite at 14.5◦, 19.87◦, and 25.6◦, with the corresponding planes of (011), (020), and (200), confirm the successful synthesis of both PANI and G/PANI nanocomposites, resulting in a more ordered structure with high crystallinity during polymerization. FTIR, UV–Vis, and Raman spectroscopy results show that strong π − π interactions aided in the uniform distribution of PANI on the rGO nanosheets. Furthermore, the XPS results demonstrate the presence of C-H, N–H, C–C, and C-O bonds, corroborating the FTIR and Raman spectroscopy findings. The electrochemical properties of the PANI-rGO confirm its possible applications as a promising electrode material for high-performance supercapacitors.
期刊介绍:
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
