Graphene has attracted much attention in recent years due to its extraordinary electronic, optical, magnetic, thermal, and mechanical properties. Despite continuing theoretical and experimental success, the unique physical properties of graphene remain underused and underappreciated. The key challenge in harnessing of the unique properties of graphene is the difficulty of reliable manipulation of well-dispersed graphene. Chemical and physical functionalization of graphene has become a focus of especial interest, because they can not only stabilize, but also induce new properties of graphene. This review summarizes the intriguing physical properties of chemically oxidized and noncovalently modified graphene, and graphene-based nanocomposites with polymer matrices or nanoparticles. Along with introducing the physical properties of functionalized graphene, their potential applications in diverse research areas are discussed.
近年来，由于其非凡的电子、光学、磁、热和机械性能，石墨烯引起了广泛关注。尽管在理论和实验上不断取得成功，但石墨烯的独特物理性能仍未得到充分利用和重视。利用石墨烯独特性能的关键挑战是难以可靠地操控分散良好的石墨烯。石墨烯的化学和物理功能化已成为特别关注的焦点，因为它们不仅可以稳定石墨烯，还可以诱导其产生新的性质。本文综述了化学氧化和非共价修饰石墨烯以及与聚合物基体或纳米粒子的石墨烯基纳米复合材料的诱人物理性质。本文在介绍功能化石墨烯物理性质的同时，还讨论了它们在各个研究领域的潜在应用。
