| Abstract: | Graphite oxide was synthesized from natural graphite powder by graphite oxidation with KMnO_4 in concentrated H_2SO_4 according to Hummers method. The component and structure of graphite oxide were investigated in detail, had on the results of IR, XRD, TG and DSC measurements. The results shows that graphite oxide possesses hydroxyl, carbonyl and other groups between the graphite Oxide lamellae. Due to the presence of these polar groups, various kinds of polar molecules and polar polymer can be inserted into the lamellae to form different kinds of intercalated graphite oxide nanocomposites. |
