Abstract
Electrochemical exfoliation is considered an essential method for the rapid production of graphene in both high quality and quantity. This study investigates the electrochemical exfoliation of graphite rods, specifically the impact of the power variations in a Direct Current (DC) source on the quality of graphene. Furthermore, Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX) is employed to analyze the morphology and elemental composition. In addition, Fourier Transform Infrared (FTIR) spectroscopy is utilized to determine the functional groups of graphene. The defect of graphite is observed with Raman spectroscopy. The SEM results suggest that graphene layers are formed in all the power variations. Graphene at 98 W (G98) exhibits a wrinkle and cluttered surface compared to graphene at 70 W (G70) and graphene at 84 W (G84). Based on the FTIR results, the highest peak of C=O bond appeared in G70, while sharp peaks indicating O-H bonds are observed in G84 and G98. Furthermore, the power analysis is a critical factor affecting graphene mass production, with higher power levels resulting in higher graphene yield, but lower graphene quality by reducing the carbon (C) content and increasing Oxygen (O) content. This exploration contributes to advancing the understanding of the electrochemical exfoliation process, offering insights into optimizing the power parameters for enhanced graphene synthesis.
