    • Abstract

       

      The Hummers method was employed in this study to oxidize fluorinated graphite. In addition, the pre- and post-chemical compositions and microstructure were characterized and analysed to explore the modification mechanism. Oxidized fluorinated graphite (OFG) with lamellar structure and variable oxygen content was obtained by oxidation method. Primarily, the oxidative modification under KMnO$_4$ is that MnO$_3$ $^+$ as Lewis acid would catalyse the activation ofthe carbon-fluorine bond, which then breaks to release a fluorine ion. Secondly, the unsaturated carbon bond would be oxidized, increasing carbon-oxygen bond content and producing some OFG nano fragments. The carbon-fluorine bond isgradually catalysed to react according to its activity as the KMnO$_4$ dosage increases, while the unsaturated carbon bond is oxidized, leaving some isolated carbon-fluorine bonds with weak activity.
