▎ 摘　　要

NOVELTY - Method for non-destructive detecting graphene point defect comprises slowly baking graphene on a metal foil in a baking device to realize optical visualization of a middle point defect of the graphene. The baking device is provided with a high temperature oxygen-containing atmosphere and a low temperature oxygen-containing atmosphere. The low temperature oxygen-containing atmosphere is provided with a high temperature oxygen-containing atmosphere and a low temperature oxygen-containing atmosphere. USE - The method is useful for non-destructive detecting graphene point defect. ADVANTAGE - The method has very simple operation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic illustration of the method for non-destructive detecting graphene point defect (Drawing includes non-English language text).
