Method and equipment for extracting carbon materials from plastics

摘要

The invention provides a method and equipment for extracting carbon materials from plastics. Particularly, the method produces nanostructured carbon materials by heating of at least one salt (e.g., NaCl) and at least one plastic material (e.g.polyethylene terephthalate) to a temperature greater than the melting point of the said salt, in which molten state of the said salt protects the carbonaceous material from oxidation. Moreover, molten salt promotes the graphitization of carbon materials. The product is in the form of graphenenano-flakes with high conductivity and high surface area. This method provides a simple, economical and efficient approach for producing conductive carbon materials. It also has a significant positive impact on the environment through the transformation of virtually non-degradable plastic wastes into high-value conductive carbon materials.
