Recently, the macroscopic assembly of graphene in forming laminar-structured films/papers draws much attention due to the close stacking layer-by-layer structure shows better performance in both electronics and energy storage applications. However, limited electrical conductivity and geometry of the patterns which fabricated by conventional solvent-based processing are far from satisfactory. In this paper, we present the self-assembly of layer-by-layer graphene via electrohydrodynamic (EHD) jet printing technique. The close-packed graphene lines with ordered film/paper-like laminar-structure could be achieved via flow and electric field induced alignment/orientation and evaporation interfacial assembly hybrid process. The surface roughness and electrical conductivity of the layer-by-layer structure were improved significantly. The solvent evaporates fast due to electric charge occurs during printing and we also successfully printed laminar graphene on the 3-D surface. We further applied this method in fabricating the graphene-based supercapacitor and a 3-D metallic grid hybrid ammonia sensor. It is believed that this EHD-assisted assembly of laminar graphene films/papers suggests a platform and promising opportunities for preparing high-performance energy storage devices and sensor.
