Graphene film electrodes have many important applications, but the fabriacion of these electrodes is difficult dues to the poor processing of graphene. This article describes the preliminary results of using 3D printing technology to fabricate thin-film electrodes from graphene oxide inks. Graphene oxide ink is synthesized by chemical method. The graphene oxide (GO) and reduction graphene oxide (r GO) thin film were chacracterized by filed scanning electron microscopy (FESEM) and Energy-dispersive X-ray spectrocopy (EDX spectrocopy) to make sure the morphological and optical characteristics of the thin film. In addition, the electrochemical aera active studies were also determined by cyclic voltametry (CV) curves. The r GO thin film displays higher electrochemical area active in comparison with GO, which is 2.56 cm2 compare to 0.31 cm2, indicating the best result for the superior conductivity of thin film electrode.
