Irradiation Effects on Nano Carbon Materials

Carbon nanotubes (CNT) and graphene are emerging materials in the nano carbon family, which have received much attention in recent years for their remarkable physical properties. The excellent electrical, thermal and mechanical properties of CNT and graphene make them to be a promising candidate for aerospace engineering. In the harsh space environment, irradiation effect may cause the damage even failure of spacecraft materials, which is the key factor to determine the application of new nano carbon materials in space engineering. This paper focuses on the recent progress of electron and ion irradiation effect on CNT and graphene. The production and the type of defects, the application of irradiation effect in material preparation and functional modification, the irradiation effect on properties of devices and the space adapt ability are discussed. The irradiation effect on nano carbon composite and the influence mechanism of defects on the properties of nano carbon systems also are discussed. By summarizing the previous researches, the current problems are listed. Finally, the future work in space application is forecasted.
