石墨烯的表面性质及其分析测试技术

Abstract

石墨烯具有特殊的二维结构和完美的物理化学性能，科研人员在这些领域做出了一系列研究成果，但对石墨烯的表面性质研究相对较少。然而，石墨烯的表面性质对石墨烯在纳米复合材料、纳米涂层以及纳米电子器件等领域的应用起着至关重要的作用。对此，笔者通过综述石墨烯表面性质以及表面改性的研究进展，着重探讨了石墨烯表面结构与表面性质间的关系；分析和比较了常用的石墨烯表面分析测试技术。进而指出制备具有特定表面性质的功能化石墨烯和开发能适应石墨烯表面性质更宽测试范围的新技术，将是今后研究的重点。最后，对石墨烯表面结构与表面性质研究中的挑战以及应用前景进行了展望。 Graphene has been paid much attention for its special two-dimensional structure and excellent physicochemical properties. Researchers have done a great number of studies on these fields, and have made lots of outstanding results, while less on the surface properties, relatively. However, the surface properties of graphene usually play an important role in the practical application of graphene-based materials, especially, in the nano-composites, nano-coating and electrical nano- devices. In this review, the recent developments of surface properties and surface modification of graphene are summarized, where the relationship between the structure and surface properties of graphene is highlighted. The method of surface testing is also compared and commented on briefly. We believe that the future prospects of research emphasis on preparation of functionalized graphene with special surface properties, and a new comprehensive technique for testing the surface properties of graphene. Finally, the current challenges of research on structural surface and surface properties of graphene are commented based on our own opnion.
