▎ 摘　　要

NOVELTY - Exfoliation of coal graphite into graphene involves smoothing coal, sieving coal powder with 325-mesh (45 mu m) sieve, heating the coal powder to 126 degrees C for 24 hours, carbonizing at 400-1200 degrees C, preferably 900 degrees C, oxidizing the carbonized product by modified Hummers method, exfoliating graphite oxide to graphene oxide, and reducing graphene oxide. USE - Exfoliation of coal graphite into graphene. ADVANTAGE - The method enables economical exfoliation of coal graphite into graphene.
