▎ 摘　　要

NOVELTY - A graphene X-ray powder diffraction characterization sample preparing method involves cutting the sponge graphene into multiple samples of different sizes, pasting them on the center of the sample table in order of size, and repeatedly pressing the sample surface until it is flat to perform X-ray powder diffraction detection, preparing a glass slide with a groove, filling the powdery graphene into the groove, after filling it, pressing the sample surface repeatedly until it is flat, and performing X-ray powder diffraction detection, preparing a glass slide with a hole in the center, after filling the hole with paste-like graphene, scraping off the excess paste-like graphene on the surface of the sample to perform X-ray powder diffraction detection. USE - Method for preparing graphene X-ray powder diffraction characterization sample. ADVANTAGE - The method enables preparing graphene X-ray powder diffraction characterization sample with improved spectrum quality, in reasonable manner.
