新型碳-碳复合材料石墨烯-金刚石研究进展
Progress of graphene-diamond as novel carbon-carbon composite
摘要
Abstract
Significance:Conventional carbon-carbon composites have evolved from disordered,low-graphitized fragments into oriented,highly graphitized microcrystals,which are now widely used in space shuttles,the automotive industry,and biomedical devices.Although their tensile strengths and electrical conductivities have been significantly enhanced,it is still difficult to further improve their mechanical strength,so a stronger carbon material needs to be introduced as a substrate.Diamond has become a key material for a new generation of semiconductors by virtue of its wide bandwidth,high breakdown field strength,high thermal conductivity,extremely high hardness,and excellent chemical stability;graphene has become an indispensable and ideal additive in the manufacture of new composite materials due to its high strength and toughness.Progress:The composite materials formed by combining diamond and graphene can significantly reduce the surface resistivity of diamond,thus improving its electrical properties.Currently,in the preparation of graphene-diamond composites,chemical vapor deposition has become the most widely used technology by virtue of its high efficiency and good process controllability.In addition,other technological routes,such as the metal-catalyzed method and the flywheel solvation method,have also been successfully realized experimentally,providing feasible technological solutions for the in-situ preparation of graphene on a diamond substrate.With the innovation of semiconductor technology,graphene-diamond composites are expected to become key supporting materials for high-power and high-frequency semiconductor devices.The core advantage of graphene-diamond composites is that they combine the extreme properties of two carbon materials,providing innovative solutions for electronic devices,energy equipment,superhard materials,and other fields.Compared with traditional carbon-carbon composites,they have less wear during the cutting process,which can greatly extend the service life of tools and reduce production costs.In addition,by combining the high thermal stability of diamond semiconductors with the high mobility of graphene,this system is expected to drive the development of fourth-generation semiconductor technology.Conclusions and Prospects:This article comprehensively reviews the research dynamics in this field,from the synthesis methods and microstructure analysis to performance optimization to the exploration of practical applications and other aspects of these materials.Carbon-carbon materials(carbon fiber reinforced carbon matrix composites,C/C composites)are widely used in aerospace,aviation,brake systems,and other fields due to their excellent high-temperature performance,low density and corrosion resistance.However,their lack of mechanical strength limits their application in the field of superhard grinding.The emergence of graphene-diamond composites fills the gap regarding the mechanical strength of carbon-carbon materials,provides the conductivity that diamond itself does not possess,and provides a solution to the brittleness problem of traditional carbon-carbon composites.关键词
