Synthesis and production of copper nanocomposite encapsulated with porous nanographene modified with poly-citric acid (Cu@PNGO-PCA) by electrodeposition method

Copper composites reinforced with porous nanographene oxide (Cu@PNGO) have many applications in modern industry. Therefore, inventing and finding a simple, low-cost, and fast industrial method on a large scale to produce this nanocomposite is considered in this study. Cu@PNGO nanocomposite was produced by electrodeposition method on the surface of the copper electrode in different concentrations of 5 % copper sulfate encapsulated in porous nano-graphene oxide. Two-dimensional porous nanographene (PNG) is created by the chemical vapor method (porous nanographene oxide (PNGO)) and to increase the solubility, PNGO nanoparticles were functionalized by poly-citric acid (PCA). Structural, electrical, and conductivity properties of nanocomposite Cu@PNGO-PCA in electrolyte solution were analyzed by energy dispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FT-IR), Scanning electron microscope (SEM) and atomic force microscopy (AFM). In this study, by increasing the voltage and material concentration in the electrolyte by deposition method, the weight percentage of nanocomposite on the electrode increased and the electrode containing copper nanocomposite shows outstanding general properties compared to the copper electrode. The addition of porous nanographene oxide enhances the nucleation process and modifies the structure of copper deposited in the cathode electrode, thus improving the mechanical properties. Altogether, this method provides a promising prospect for mass and rapid production of porous nanographene oxide-reinforced copper nanocomposites with excellent overall properties that are well compatible with current copper industry technology at a lower cost.
