▎ 摘　　要

NOVELTY - A graphene detecting method involves measuring amount of residual carbon of the blank masterbatch containing no graphene and denoting as a, measuring amount (b) of residual carbon of the composite masterbatch doped with graphene and denoting as b, and measuring amount of residual carbon used as graphene dopant and denoting as c, followed by calculating the graphene content in the composite masterbatch. USE - Method for quantitatively detecting graphene in a composite masterbatch. ADVANTAGE - The method enables the detecting graphene in simple, rapid and quantitative manner.
