▎ 摘　　要

NOVELTY - High temperature rapid quenching of highly conductive thin layer graphene comprises (i) placing graphene in a high temperature furnace, and calcining at 300-750 degrees C for 1-20 minutes; (ii) transferring the graphene into a refrigerant and quickly quenching; and (iii) boiling refrigerant under normal temperature and pressure conditions so as to volatize it, and collecting the thin layer of graphene. USE - The method is useful for high temperature rapid quenching of highly conductive thin layer graphene (claimed). ADVANTAGE - The method is easy to implement, requires low investment, has simple operation and low cost.
