Electrical and structural behavior of copper nanocomposites encapsulated with modified graphene oxide graft and carbon nanotubes (cu@GO-g-CNTO-amine/PCA) on copper pieces

In this study, nanocomposite coating of encapsulated copper is developed among the branches of carbon nanostructures (graphene oxide graft and carbon nanotube oxide (GO-g-CNTO)) functionalized with poly citric acid and urea on copper electrode by electrodeposition method. Increasing the percentage of Cu@GO-g-CNTO-amine/PCA nanocomposite in the electrolyte affected the surface morphology and improved the granularity of the coated copper particles. The uniform distribution of particles on the surface increased the electrical properties, current density, strength, and other properties because the improvement of the structural factors controls the mechanical behavior of the parts. The structure of the coatings and their performance were investigated by Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray energy diffraction spectroscopy (EDX), and Atomic force microscopy (AFM). The results show that by modifying the surface of carbon nanostructures with poly citric acid and urea, in addition to increasing their solubility, the thickness of the copper coating can be controlled. The use of urea in the reaction reduced the corrosion and oxidation of the surface and increased the electrical and mechanical properties of the surface.
