ResumoReduced graphene oxide nanoribbon fibers were fabricated by using an electrophoretic self-assembly method without the use of any polymer or surfactant. We report electrical and field emission properties of the fibers as a function of reduction degree. In particular, the thermally annealed fiber showed superior field emission performance with a low potential for field emission (0.7 V µm−1) and a giant field emission current density (400 A cm−2). Moreover, the fiber maintains a high current level of 300 A cm−2 corresponding to 1 mA during long-term operation.
