Graphene oxide (GO) samples with different oxidation degrees were prepared using the modified and improved Hummers’ method by varying the ratios of graphite to potassium permanganate (KMnO4) at 1:2 (GO1), 1:4 (GO2), 1:6 (GO3), and 1:8 (GO4). Fourier-transform infrared spectroscopy (FTIR) and Raman s...
