石墨烯的共价键功能化研究进展

摘要

In order to improve the drawbacks of graphene that limit its performance, such as low solubility and poor dispersion in water or ordinary organic solution, the functionalization of graphene becomes a hot area of research currently. Graphene can be functionalized by covalent bond, and it can also be functionalized by non-covalent bond. The recent progress of covalent bond functionalization of graphene, including functionalization by organic small molecules and polymer, were summarized. The advantages and disadvantages of covalent functionalization of graphene were analyzed. Meanwhile, the development trends of the functionalization of graphene was pointed out.%为了克服石墨烯不溶于水及常见有机溶剂的缺陷，并扩展石墨烯的应用范围，就有必要对石墨烯进行功能化。共价键功能化和非共价键功能化是石墨烯功能化常见的两种方式，其中石墨烯的共价键功能化主要包括有机小分子共价键功能化和聚合物共价键功能化等。本文综述了近年来石墨烯共价键功能化方面的研究进展，比较了石墨烯共价键功能化和非共价键功能化的不同之处，对石墨烯共价键功能化的发展前景进行了展望。
