For the possible applications of graphene, graphene flakes prepared from direct exfoliation of natural graphite and/or from a reduction of graphene oxides (GOs) have been widely investigated in various fields. Herein, we like to present novel synthetic scheme with new reduction condition of GO to reduced graphene oxides (rGOs). For mass-production of graphene flakes, a chemical graphitization from graphene oxide (GO) to rGO was introduced at a room-temperature. New reducing reagent, hydroiodic acid in acetic acid (HI-AcOH), was introduced from GO to rGO, leading to one of best reduction method in solution- and vapor-phase. We also like to introduce the fabrication of a non-volatile molecular memory device using rGO-Au nanoparticles and our recent research results in the field of graphene flakes. Finally, we like to introduce our on-going researches of the graphene flakes and their possible applications in the various research fields. |
