“梦想照进现实”——从富勒烯、碳纳米管到石墨烯

Dreams may come:from fullerene,carbon nanotube to graphene

从富勒烯、碳纳米管到石墨烯,过去25年见证了碳的三种同素异形体的发现和快速发展。石墨烯作为理想的二维碳纳米结构,表现出很多奇特的物理化学性质。物理学家和化学家对待石墨烯不同的研究视角以及石墨烯对于物理学家和化学家的不同意义在于:前者的任务是发现极限结构的奇特性质,而后者主要着眼于基于石墨烯的碳纳米结构可控构建和有效调控。化学家另外一项重要任务是解决石墨烯的制备科学问题,而温和条件下"热化学解理"是实现石墨烯规模制备、进而推动石墨烯研究快速发展的重要解决方案之一。

The past twenty-five years have seen the discovery of three new carbon allotropes：fullerene,carbon nanotubes and graphene.Graphene,with an ideal two-dimensional structure,demonstrates many unique physical and chemical properties.This short review presents different ＂faces＂ of graphene in the eyes of physicists and chemists.For physicists,graphene means the thinnest platform to reveal new or unexpected properties of materials,while,for chemists,graphene acts as a basic and starting unit for desired structures with tuned properties.Thermal chemical exfoliation under mild and well-controllable conditions is highlighted as a feasible solution for the realization of mass-production and early applications of graphene-based materials.
