Copper-Graphene Composite: Electrochemical Synthesis and Structural Characterization

Abstract

Graphene utilization as multifunctional conductive material still has been obstacled in the scalling up process. Some methods, such as mechanical exfoliation only results few products, otherwise Chemical Vapor Deposition (CVD) needs high cost and high temperature. Synthesis of copper modified graphene by electrochemical with low cost has been studied in this research. Cu-Graphene composite was characterized using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM). XRD analysis indicates conformity with simulated pattern peaks 2θ at 26.73°; 31.9° and 45.8°, that shows presence of graphene and Cu. In addition, SEM analysis shows that the Cu-Graphene morphology was in exfoliated flake structure. The electrochemical method performed here is expected can be used for scaling up the Cu-graphene production.
