Synthesis Of Nanographite-Ribbon

Graphitic materials in nanometer size (nanographite) having edges of carbon hexagonal bond network is in very recent years attracting much attention because the theoretical approach has shown that such a nanographite is able to have a special electronic state at the edges, especially the zigzag ones. We have succeeded in synthesizing the nanographite by means of electrochemical reduction following electron beam irradiation for per-fluoro-aromatic pitch and by means of thermal decomposition of hydrocarbon polymers. The structural properties of graphitic materials were investigated using x-ray photo-electron spectroscopy, Raman scattering spectroscopy, x-ray diffraction measurements and electron microscopy. In this work, ribbon-shaped nanographite (nanographite-ribbon) in a thickness of below 10 nm having the edges was obtained. The structure of the nanographite-ribbon will be discussed.
