摘　　要：石墨烯作为一种苯结构无限延伸的纳米与介观分子,表现出多层次迥异的物理与化学特性.本文从机械剥离法制备的石墨烯的奇特物理性质追溯氧化石墨烯(GO)相关化学反应的开展,再到其共价/非共价功能化及应用,用分级化学的视角梳理了该领域的化学进展.重点论述了化学方法制备的氧化石墨烯及还原氧化石墨烯(rGO)在溶液分散态下的功能化方法和自组装结构.针对环境友好的可溶液加工GO/rGO工艺面临的问题,总结了纳米片分散性、片间相互作用及其薄膜工艺的相关进展,为研究其墨水配方、成膜工艺和薄膜微结构的控制提供了指导.最后在总结rGO薄膜材料相关研究进展的基础上,介绍了其在智能信息器件中的应用,并对存在的挑战性问题和未来研究方向提出自己的观点.Graphene,as a kind of nano and mesoscopic molecule which consists of one-atom-thick planar sheet comprising sp2-bonded carbon structure with exceptionally high crystal and electronic quality,shows hierarchical different physical and chemical properties and has been emerged as a rapidly rising star in the field of material science.Graphene has caused much concern in many areas of science and technology due to its remarkable properties.These properties include extraordinary mechanic performances,high specific surface areas and electron transport capabilities.These unique physicochemical properties suggest that graphene has great potential for providing new approaches and critical improvements in the field of information devices.In recent years,many reviews focusing on graphene and related materials have been published.In addition,several reviews with particular emphasis on information devices based on graphene related materials have been reported.One specific branch of graphene research deals with graphene oxide(GO)and reduced graphene oxide(rGO).GO can be considered as a precursor to graphene synthesis by either chemical or thermal/light reduction processes.GO consists of a single-layer of graphite oxide and is usually produced by the chemical treatment of graphite through oxidation,with subsequent dispersion and exfoliation in water or suitable organic solvents.With respect to its structure,there have been several structural models proposed over the years.These assume the presence of various oxygen functional groups in the GO.The oxygen functional groups have been identified as mostly in the form of hydroxyl and epoxy groups on the basal plane,with smaller amounts of carboxyl,carbonyl,phenol,lactone,and quinone at the sheet edges.The chemical reduction of graphene oxide is a promising route towards the large scale production of graphene for commercial applications.The electrical conductivity of the functionalized graphene has been observed to decrease significantly compared to pure graphene,moreover,the surface a
