【摘要】 氧化石墨是石墨经液相氧化得到的一种具有准二维层状结构的共价键型石墨层间化合物。这种氧化作用既可发生在石墨表面,也可发生在石墨层间,并赋予氧化石墨良好的表面化学特性和插层化学特性,具有许多潜在的应用前景。本文在简单回顾氧化石墨发展历史的基础上,阐述了近年来国内外在氧化石墨的制备、结构、性质及应用等方面开展的研究工作和取得的进展,包括制备氧化石墨的三种方法,已提出的几种氧化石墨结构模型的比较,氧化石墨的层离性质、电学性质、热稳定性质、氧化还原性质和离子交换性质、以及聚合物/氧化石墨纳米复合物在作功能膜材料、导电材料和阻燃材料等方面的应用前景和目前的研究开发现状。更多还原

【Abstract】 Graphite Oxide (GO) is a pseudo-two-dimensional graphite intercalated compounds with covalent bond which is prepared though liquid oxidizing of graphite. The oxidation can occur on the graphite surface and between the layers of graphite, which endows GO with excellent surface chemistry and intercalation chemistry with the result that GO has wide potential applications. This paper simply reviewed the research history of GO firstly, then introduced the research progress in preparations, structures, properties and applications of GO, including three preparation technique of GO, the contrast among several provided structure models of GO, and characters of GO, such as intercalation, electrical properties, thermal stability, redox and ion exchange capacity. And the studies of polymer/GO nanocomposites were also summarized as functional films, conductive materials and flame-retardant materials and so on.更多还原
