Title:
METHOD FOR EXTRACTING CARBON MATERIAL FROM PLASTIC AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/222906
Kind Code:
A1
Abstract:
Provided are a method for extracting a carbon material from plastic and a device therefor. The method comprises subjecting at least one plastic material (such as a polyterephthalate salt) to a heat treatment in at least one molten salt (such as NaCl) until above the melting point of the molten salt so as to form a nanostructured carbon material, wherein the salt is in a molten state, and thereby the carbon material is protected from oxidation; moreover, the molten salt facilitates the further graphitization of the carbon material, and the product therefrom is a graphite nanosheet with a high electrical conductivity and a high surface area. The method provides a simple, economic and efficient way for producing conductive carbon materials. The method also produces a significant positive effect on the environment by converting almost non-degradable plastic waste to high value conductive carbon materials.
