Abstract: 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.

Abstract: The present disclosure relates to a polymer-based large-area carbon nanomesh and a method for preparing the same. More particularly, the present disclosure provides a method for preparing a carbon nanomesh such as graphene nanomesh, including: preparing a polymer nanofilm by coating a solution of a block copolymer or a polymer mixture thereof on a substrate; stabilizing the polymer nanofilm by annealing such that the polymer nanofilm is phase-separated, a hole-forming polymer is removed and, at the same time, a nanomesh-forming polymer is cyclized and forms a stabilized polymer nanomesh; and carbonizing the stabilized polymer nanomesh by annealing at high temperature to prepare a carbon nanomesh. Using the phase separation and cyclization, a large-area carbon nanomesh with superior activity can be prepared simply with high reproducibility in large scale.
