Abstract: Provided are a method for preparing a carbon material using a polyolefin-based plastic, which includes a step of dissolving a polyolefin-based plastic in a solvent and then precipitating to obtain a polyolefin-based polymer having, for example, a powder or film shape, a step of crosslinking and cyclizing the precipitated polyolefin-based polymer to stabilize the polyolefin-based polymer and to cleave linear bonding of the polyolefin-based polymer, and a step of carbonizing the stabilized polyolefin-based polymer and a carbon material prepared according to this method. According to this method, it is possible to convert polyolefin-based plastics, particularly polyolefin-based waste plastics, into high-quality carbon materials having high heat-generating properties and a high electrical conductivity by a simple and efficient process.

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.
