摘要
Provided is a method for preparing a carbon material based on an organic nanofilm using thermal evaporation, including: depositing a liquid polymer or polymer solution containing a polymer and a solvent onto a substrate, thereby forming an organic nanofilm; stabilizing the organic nanofilm so that the carbon atoms in the organic nanofilm have a cyclic arrangement; and carbonizing the stabilized organic nanofilm, thereby forming a carbon material, wherein the organic nanofilm is formed from the liquid polymer or polymer solution through a thermal evaporation process. The method provides a carbon material with a thickness, sheet resistance and surface roughness suitable for various applications and allows control thereof. In addition, the method uses a relatively inexpensive starting material, pitch, thereby reducing the overall production cost, and avoids a need for a complicated additional patterning operation, so that the carbon material is applied directly to electronic devices.
