【摘要】 在Ｈｕｍｍｅｒ法的基础上合成了氧化石墨，对氧化石墨的组成、分子结构及其还原性进行了测试与分析，结果表明，氧化石墨结构中含有大量的极性基团，这些基团的存在赋予了氧化石墨在极性溶剂中有良好的溶剂化能力。更多还原

【Abstract】 Graphite oxide was synthesized from natural graphite powder by graphite oxidation with KMnO₄ in concentrated H₂SO₄ 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.更多还原
