Growth of Graphene Pattern from Polymer with UV Irradiation |
| 초록 |
The patterning of graphene has received a great attention, because it is essential to be utilized practically. However, when a top–down method is employed, the excellent property of graphene is lost due to the disordered structure in the edge. Here, we introduce a direct patterned growth of graphene on poly(styrene) (PS) film via UV irradiation. Because PS is crosslinked by UV-irradiation, a selective cross-linked region is prepared on the PS film/copper foil. When the sample is heated a high temperature under 1 Torr of Ar/H2 atmosphere, only non-crosslinked regions are converted into grapheme, while cross-linked regions becomes amorphous carbon. The patterned grapheme is characterized by Raman spectroscopy, scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). |
