▎ 摘　　要

NOVELTY - The method involves allowing (a) oxygen or water molecules to react to the copper foil of the first layer through the defective portion of the graphene of the second layer. The entire region is set (b) according to the number of partial regions designated by the user such that each partial region is arranged in the entire region of the graphene-synthetic copper foil. Each of the partial regions is photographed (c) to obtain images of partial regions. An oxidized region of the copper foil of first layer is detected (d) for each of the images of partial region after removing the image of wrinkles of graphene-synthetic copper foil. A ratio of the graphene defect area to the total area is obtained (e) for each of the images in the partial region. The different colors are set for each section with respect to the ratio of the graphene defect area of 0 to 100%, and a set color is applied to the ratio of the graphene defect area of each of the images of the partial area to be displayed. USE - Method for inspecting synthesis quality of graphene. ADVANTAGE - The graphene defect regions are quickly detected in each of the images of the partial region by using a photographing apparatus capable of scanning the XY axis. Since the graphene defect areas are quickly detected, the ratio of the graphene defect area is quickly determined. Since the ratio of the graphene defect area to the total area is obtained for each of the images in the partial region, the degree of graphene defect is quantitatively and accurately identified, and state of the entire region of graphene is effectively monitored. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a system for inspecting synthesis quality of graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for testing graphene.
