石墨烯独特的热，电和机械性能源于其结构，包括单原子厚度，二维和广泛共轭。这些结构元素赋予石墨烯有利的热、电和机械性能。然而，石墨烯的应用受到生产，储存和加工问题的挑战。因此，石墨烯的稳定化和改性引起了人们的广泛兴趣。本文综述了石墨烯的化学改性策略、改性对石墨烯的影响以及石墨烯在各个领域的应用。一般来说，化学修饰可以通过共价或非共价相互作用来实现。共价修饰通常会破坏一些石墨烯共轭系统，导致其一些性质受损。因此，本文主要介绍了非共价修饰方法，如π-π堆积作用和货车范德华力，因为非共价修饰被认为是保持天然结构和性质的方法。我们还讨论了与生产，加工和性能增强相关的挑战。本文还讨论了沿着石墨烯的电学、力学和其他性质的控制，以及在更温和的条件下制备大尺寸石墨烯的前景。
Graphene's unique thermal, electric and mechanical properties originate from its structure, including being single-atom thick, two-dimensional and extensively conjugated. These structural elements endow graphene with advantageous thermal, electric and mechanical properties. However, the application of graphene is challenged by issues of production, storage and processing. Therefore, the stabilization and modification of graphene have attracted extensive interest. In this review we summarize the strategies for chemical modification of graphene, the influence of modification and the applications in various areas. Generally speaking, chemical modification can be achieved via either covalent or non-covalent interactions. Covalent modifications often destroy some of the graphene conjugation system, resulting in compromising some of its properties. Therefore, in this review we focus mainly on the non-covalent modification methodologies, e.g. π–π stacking interactions and van der Waals force, because the non-covalent modifications are believed to preserve the natural structure and properties. We also discuss the challenges associated with the production, processing and performance enhancement. Future perspectives for production of graphene in large size with fewer defects and under milder conditions are discussed along with the manipulation of graphene's electric, mechanical and other properties.
