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.
