グラファイト系炭素の次元性と応用

抄録

It reports on the advancement of a recent graphitized carbon material from the viewpoint of dimensionality and application. First of all, the dimensional change and the possible application of fullerene (zero-dimensional graphite), carbon nanotube (one-dimensional), and graphene (two-dimensional) are described. The synthesis of the unique graphite fiber is also mentioned, as an example of obtaining a graphitized material in various forms by the molecular structure of the raw material. Next, making of a high-quality graphite film from a polyimide and its optical and thermal applications are described. It introduces the research of the pressure-induced phase transition from the graphite film to diamond.
