Abstract Scope |
Graphene has been extensively investigated for future industrial applications because of its outstanding mechanical and electrical characteristics. The chemical oxidation of graphite and subsequent production of monolayer graphene oxide (GO) are one of the promising mass production methods of graphene. However, since GO is electrically insulating, its conversion to electrically conductive forms is inevitable for practical applications. The chemically or thermally reduced graphene oxide (rGO) has diverse properties depending on the process conditions. In this study, the electrical conductivity of rGO powders was characterized under compression according to the thermal reduction conditions. In addition, the mechanical work required to compress the various shapes of rGO powders was measured. This work provides a fundamental understanding of the rGO powders using the electro-mechanical measurements and will be useful for commercialization of rGO powders. |
