| 논문초록 | In this study, thermal oxidation, which has only been considered as a degradation pathway for thermo-plastics, served as a simple and effective pre-treatment method to convert the chemical structure of ‘non-carbonizable’ linear low density polyethylene (LLDPE) for successful carbonization. Interestingly, LLDPE based carbon could be graphitized into a highly ordered graphitic carbon with exceptional electrical performance exceeding that of Super-P, a pricey reference conductive agent for lithium ion battery fabrication. Upon thermal oxidative pre-treatment, inherently non-carbonizable LLDPE was successfully transformed into an ordered carbon through heat treatment with a high conversion yield reaching 50 %. Finally, LLDPE waste, such as cling wrap and poly-gloves was also successfully converted into an ordered carbon comparable to that obtained from the as-produced LLDPE precursor, suggesting opportunities associated with ‘upcylcing’ of waste products. |
