Tuning the ratio of sp2/sp3 is crucial factor for obtaining high aspect ratio of graphene oxide. In this work, we reported a comprehensive study on synthesis of GO with different sp2/sp3 ratios at different oxidation reaction temperatures. The physicochemical properties of the as-prepared GO were ch...
