In this study, the electrical properties of exfoliated graphite (EG) with copper addition is reported. Firstly, EG samples were synthesized using electrochemical exfoliation of the pre-treated graphite sheet then combined with various copper concentrations. X-Ray Diffraction (XRD) characterization indicated that the composites of EG, Cu, and Cu 2 O were formed. A higher Cu 2 O amount obtained when the higher concentration of copper precursor was added in the EG. Scanning Electron Microscopy (SEM) images showed that more particles with larger sizes were anchored on the EG surface as higher copper concentration. The electrical properties of the samples were measured using the four-point probe method. The highest electrical conductivity of 37.86 S/cm was produced in the EG sample with 1 wt.% of copper addition. The result reveals that the optimum copper addition can increase the electrical properties of EG.
