Graphene powders obtained via the reduction of graphene oxide flakes have been widely used in various applications as they can be synthesized in large quantities with outstanding properties. The electrical conductivity of graphene powders is critical for their uses in fabricating high-performance devices or materials. Here, we investigated the bulk electrical conductivity of reduced graphene oxide (rGO) powders depending on the applied pressure and additional thermal annealing. The electrical conductivity of the rGO powders was correlated with the change in the carbon-to-oxygen ratio via additional thermal reduction. Furthermore, the effect of the morphology of the rGO powders was studied through electromechanical measurements. This study provides a reliable method for the electromechanical characterization of rGO powders and a better understanding of the electrical conductivity of graphene-based materials.

AbstractGraphene oxide (GO) macroscopic films, fibers, and membranes have become important applications of this interesting two-dimensional material due to their specific properties and great potential as new high-performance materials. After chemical or thermal reduction, GO is transformed into an electrically conductive material termed reduced GO (RGO). These materials hold great potential because they can be prepared in large quantities at low costs, and consequently they are particularly suitable for applications in packaging, textiles, energy devices, and separation technologies. In the following years, the use of GO- and RGO-based films, fibers, and membranes is expected to grow; however, several challenges regarding its processing conditions must be resolved. In this review, we addressed some of the recent work regarding these important technologies and summarized the state of the art of GO films, fibers, and membranes.
