CARBON MATERIALS BASED ON ORGANIC NANO FILM USING THERMAL EVAPORATION AND METHOD FOR PREPARING THE SAME

摘要

The present invention relates to an organic nanofilm based carbon material using thermal deposition and a method for producing the same. The method for producing the organic nanofilm based carbon material using thermal deposition according to the present invention comprises: an organic nanofilm production step of depositing a polymer liquid or a polymer solution including a polymer and a solvent over a substrate to produce an organic nanofilm; a stabilization step of stabilizing the organic nanofilm for carbon atoms in the organic nanofilm to have a ring sequence; and a carbon material production step of carbonizing the stabilized organic nanofilm to produce a carbon material. As the organic nanofilm production step is configured such that the polymer liquid or the polymer solution is deposited over the substrate through a deposition method using heat, the produced carbon material has a material thickness, surface resistance, and surface roughness suitable for application fields as well as be able to control the material thickness, surface resistance, and surface roughness. Furthermore, a pitch, which is a relatively inexpensive raw material, can be used in the present invention to cut the total production cost as well as to omit extra complex patterning processes so that the organic nanofilm based carbon material can be directly applied to an electronic device.
