Tailored Assembly of Chemically Modified Graphitic Carbon Nanomaterials

摘要

Since the first discovery of fullerene in 1985, graphitic carbon materials including fullerene, carbon nanotubes (CNTs), and graphene/ have been of central research interest in materials science. Recently, the rapid progress of graphene based materials has again triggered tremendous interest in graphitic materials. While fullerene has a zero-dimensional shape with a discrete molecular weight, CNTs and graphene have anisotropic one- and two-dimensional shapes, respectively, with broad distributions of their molecular weights. Despite such morphological diversity, all graphitic carbon materials consist of two-dimensional conjugated sp~2 hybrid carbons. This unique chemical structure provides a broad spectrum of outstanding properties, such as exceptional charge-carrier mobility, large charge-storage capacity and mechanical flexibility, which are potentially useful in overcoming the fundamental limitations of conventional electronic and energy devices.
