纳米碳材料是过去30年间最为活跃的研究领域之一.富勒烯、碳纳米管、石墨烯等一系列碳质新材料先后被发现,带来了丰富的新结构、新现象、新物理和新应用,掀起并带动了持续至今的纳米科技研究热潮.纳米碳材料之所以受到广泛关注是因为其特有的几何结构、以sp2杂化为主的成键方式以及由此带来的优异的电学、力学、热学、光学等特性.例如,碳纳米管和石墨烯分别是已知最细和最薄的材料,具有远高于硅的载流子迁移率、最高的热导率和力学强度,以及优异的柔韧性.纳米碳材料的性能对结构变化极其敏感,如手性
Nanocarbon materials have been one of the most active research fields in the past 30 years, and a series of new carbon materials such as fullerenes, carbon nanotubes and graphene have been discovered, resulting in rich new structures, new phenomena, new physics and New applications, set off and led to the continuing upsurge in nanotechnology research.Carbon nanomaterials have attracted widespread attention because of its unique geometry, sp2-based hybrid bonding method and the resulting excellent electrical Such as mechanical, thermal, optical, etc. For example, carbon nanotubes and graphene, respectively, are the thinnest known and thinnest materials, with much higher carrier mobility than silicon, highest thermal conductivity and mechanical strength, As well as excellent flexibility.The properties of nanocarbon materials are extremely sensitive to structural changes such as chiral
