▎ 摘　　要

NOVELTY - The method involves cleaning and cutting the waste plastic to obtain the pretreated waste plastic. The substrate material and the pretreatment waste plastic are sequentially placed in the quartz tube of the plasma system, followed by heating, introducing argon gas, and performing plasma deposition to obtain the vertical graphene nanosheet array on the substrate. USE - Method for converting waste plastic into vertical graphene nano-sheet array in field of solid waste treatment and resource utilization. ADVANTAGE - The method uses the common waste plastic as raw material, using plasma technology to quickly prepare the graphene added value of the nano-sheet array, at the same time, the graphene substrate of the nanosheet array is wide. The graphene prepared nano- sheet array has many advantages: it is effectively bonded with the substrate and is not easy to be stripped, chemical, strong heat and mechanical stability, ultra-large specific surface area, a large number of graphene blade edges with chemical reaction activity, an open porous structure which is easier to be infiltrated by the electrolyte than other three-dimensional structures, high conductivity and so on. Due to the excellent properties, the vertical growth graphene the array structure is one of the most ideal carriers for electrochemical reaction electrodes or other active materials in electrochemical reactions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a vertical graphene nano-sheet array prepared by the method for converting waste plastic into vertical graphene nano-sheet array. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating the Raman spectrum of an array of vertical graphene nanoplatelets prepared.
