| Research Abstract |
Solution processable few layer graphene is an intriguing nanomaterials for novel electronic application such as printable electronics. In this study, few-layer exfoliated graphenes were obtained by the novel electrochemical exfoliation method using salt electrolyte such as sodium sulfate. Use of the salt electrolyte can be protected the earth's environment compared with present graphite exfoliation using strong oxidant. In addition, we elucidate that the thickness of electrochemical exfoliated graphene can be controlled by the ion species, concentration of salt electrolyte, and applied potential for graphite. These graphenes were not modified any functional groups without any treatment. We demonstrate to make the transparent conducting films using the exfoliated graphene.
