| Outline of Final Research Achievements |
Liquid phase exfoliation that enables to produce few-layer graphene from graphite has been developed in order to improve the quality and yield of graphene. It was demonstrated that the pressure homogenizer produced few-layer graphene more than ten times compared to conventional sonication method. We have found the optimal solvent system. The cosolvent of organic solvent and alkali water was the most proper solvent in liquid phase exfoliation due to its enhanced steric and electrical repulsion forces. In addition, we can successfully modify the structure of graphite. The modified graphite can be dissolved in water and alcohol those of which are believed as incompatible solvent against graphite.
