氧化石墨烯的制备、结构控制与应用

Preparation,structure control and application of graphene oxide

石墨烯具有卓越的力学、电学、热学和阻隔性能,但疏水性、生物不相容性等缺点限制了其在诸多方面的应用。氧化石墨烯(GO)为石墨烯的衍生物,是一种新型的碳材料,边缘处具有羧酸官能团并且其表面含有羟基和环氧基团,具有良好的分散性、双亲性、生物相容性等性能,被视当代最具有发展前景的碳材料之一。本文简述了氧化石墨烯的结构模型、制备方法和官能团可控氧化石墨烯的制备,介绍了氧化石墨烯的性能和的应用进展,分析了氧化石墨烯在制备和应用方面的一些不足。最后,阐述了石墨烯未来面临的挑战以及潜在的发展前景。

Graphene has excellent mechanical,electrical,thermal and barrier properties,but its shortcomings such as hydrophobicity and biological incompatibility have limited its application in many aspects.graphene oxide(GO),a derivative of graphene,is a new type of carbon material.graphene oxide with carboxylic acid functional groups at the edges and hydroxyl and epoxy groups on its base has good dispersion,amphiphilicity,biocompatibility,etc.graphene oxide is regarded as one of the most promising carbon materials in the contemporary era.This paper briefly described the structure model,preparation method and functional group controllable of graphene oxide.The properties and application progress of graphene oxide were introduced,and some deficiencies of graphene oxide in its preparation and application were analyzed.Finally,the future challenges and potential development prospects of graphene were discussed.
