石墨烯薄膜对铜及镍防腐蚀性能的研究进展

Research Progress of Graphene Film as Protective Coating for Copper and Nickel

石墨烯是由碳原子以sp2杂化连接的单原子层构成的,具有非常优异的热学、电学和机械性能。石墨烯已经应用于太阳能电池、超级电容器、气体传感器、场效应晶体管、催化剂和药物载体等方面,由于石墨烯具有非常好的热稳定性和化学惰性,石墨烯薄膜可以应用在金属的腐蚀防护方面。本文主要介绍了石墨烯薄膜对金属铜和镍耐化学介质的性能。

Graphene is a monoatomic layer sheet,formed by a hexagonal arrangement of carbon atoms with excellent thermal,electrical and mechanical properties.Graphene has been used in solar cells,super capacitors,gas sensors,field effect transistors,catalysts and drug carriers,etc.Due to the high thermal stability and chemical inertness,the graphene film can be used to protect metals as well.In this paper,the research progress of graphene films used for protecting the surface of the metallic growth substrates of Cu and Ni alloys from air oxidation and other solutions is discussed.
