| Research Abstract |
We have found effective formation conditions of graphite nanoplatelets (GNP) by “metal-free arc plasma heating”, and observed coercivity of 0.1kOe. Furthermore, we have found that heat treatment in hydrogen of reducing atmosphere enabled to improve graphitic structure. We have clarified that carbon naofibers (CNFs) grown by “metal-free thermal chemical vapor deposition” have a very small amount of sulfur atoms (ca. 0.02%) in the carbon network of the CNFs via elemental analyses. We have realized that the metal-free CNFs were formed on surfaces of a quartz frosted glass about 30 times as much as before via improvement of the process.
