摘　　要：掌握氧化石墨烯(Graphene oxide, GO)的结构是理解其性质并付诸应用的基础,然而GO的官能团种类及排列方式繁杂。大多数实验得到的官能团等数据相似,但在数据的解读尚未达成统一。目前广泛认可的GO模型有LK模型、动态结构模型和二组分结构模型等。GO的结构继承了其前驱体氧化石墨的成果—LK模型,这一模型被广泛用于解释GO的绝缘性和亲水性等。然而LK模型近年来也受到许多新的研究挑战。Dimiev根据酸性起源的研究提出了GO的动态结构模型,认为GO的结构在液相制备和存放中不断改变。而Rourke等则根据纳米碳管的酸化氧化研究,提出GO的二组分结构模型,将GO分为完整片层和氧化碎片两部分,分别从二者性质出发解释GO的性质。The structure of graphene oxide (GO) is fundamental to understanding its properties and to realizing its applications. Experiment observations of the GO structure from different researchers are similar. However, the interpretation of the experimental data is still controversial due to the complicated oxygen functionalities and their arrangement. The Lerf-Klinowski structural model is one of the most popular used to fit experimental data and explain properties such as hydrophilicity and electrical resistivity. However, it has been challenged by new findings, and new structural models have been proposed in recent years. Based on the acidity of GO, Dimiev et al. proposed a dynamic structural model to explain the structure change of GO during its preparation and preservation in water. Rourke et al. proposed a two-component structural model to account for the acidification and oxidation behavior.
