Graphene was synthesized by the modified Hummers method and a hydrazine reduction process. The obtained graphene was characterized by various diagnostic techniques, such as scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). A layer of transparency crumpled film was obtained with an interlayer spacing of 0.37 nm. The two typical peaks of 3415 and 1091 cm −1 correlated to OH and CO were observed from the FTIR spectrum. The samples showed an enhanced thermal stability promoting the way for the research and the applications of graphene.
