Graphene, one of the allotropes of carbon, has widely received much attention because it has outstanding properties such as optical, electrical, and mechanical properties. For applying various applications, graphene should be transferred to the target substrate, the significant defects (e.g., cracks and wrinkles), however, have been inevitably generated at this stage. It significantly limited to the various potential applications. In this presentation, a novel method is described for the direct growth of patterned graphene on dielectric substrates by chemical vapor deposition (CVD) in the presence of Cu vapor and using a solid carbon source, 1,2,3,4-tetraphenylnapthalene (TPN), as the precursor. The UV/Ozone treatment of the TPN film both crosslinks TPN and results in a strong interaction between the substrate and the TPN that prevents complete sublimation of the carbon source from the substrate during CVD. Substrate-adhered crosslinked TPN is successfully converted to graphene on the substrate without any organic contamination. The graphene synthesized by this method shows excellent mechanical and chemical stability. This process also enables the simultaneous patterning of graphene materials, which can thus be used as transparent electrodes for electronic devices. The proposed method for the synthesis directly on substrates of patterned graphene is expected to have wide applications in organic and soft hybrid electronics.
