  • In this article, Cu-Gr composite thin films are prepared by electrodeposition route using in-house synthesized graphene sheets. Graphene sheets are synthesized by the electrochemical exfoliation route using 1M HClO4 acid as electrolyte. Graphene sheets have been confirmed by XRD, FTIR, FESEM and TEM microscopy. The (002) plane of graphene sheets are observed at 2θ of 25.66⁰. The (002) plane confirms the crystal structure of carbon peaks. The stretching vibration of C=C bond at a wavelength of 1577 cm-1 and other functional groups of carboxyl and epoxide groups have been observed from FTIR. TEM microscopy confirms the transparent structure of graphene sheets. The prepared graphene sheets were used as reinforcement in concentration of 0.1 g/L and 0.3 g/L with a copper matrix to synthesize Cu-Gr composite. The prepared composite thin films have been characterized by XRD, SEM and EDS for morphological and analytical study. The presence of graphene sheets in Cu-Gr composite was confirmed by EDS analysis. The prepared Cu-Gr nanocomposite thin film shows higher corrosion resistance as compared to pure copper thin films in 3.5% NaCl as confirmed by Tafel plots. EIS also compliments the above results, which shows that 0.3 g/L composite film has highest film resistance.
