▎ 摘　　要

NOVELTY - The method involves preparing an oxidized graphene dispersion slurry. The slurry is adsorbed by using a sampler. Two transparent film sheets are arranged in the middle of the slurry to prepare a sandwich structure of a sandwich-like structure. The sandwich structure is placed under the transparent square grid scale line sheet. A camera is used to shoot a picture record. The obtained picture middle area is selected to obtain a 3x 3 grid. The black particulate matter visible to the naked eye in the grid is counted. The total number is marked as N, where the particulate amount of each grid is N/9, and the number of the particulate area N/81, and the H value is 81/N. USE - Method for detecting uniformity of oxidized graphene. Uses include but are not limited to heat conducting material, electrochemical energy storage, catalysis, biological medicine and composite material. ADVANTAGE - The method enables using the difference of the dispersibility of the graphite completely oxidized and partially oxidized or not oxidized in the water. The uniformity of the oxidized graphene product is judged by the image display method. The method enables testing the light transmission effect of the film spread by the product slurry by macro sampling, the light shielding property is considered as particulate matter uniformly dispersed in the product, and it is quantized, the particulate matters of the product is evaluated. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an AFM test result of graphene oxide.
