▎ 摘　　要

NOVELTY - Preparing graphene comprises (i) uniformly dispersing a graphite microchip in a medium system to obtain a dispersion, (ii) uniformly mixing the dispersion in a mixing device, and physically stripping the obtained mixture to obtain a crude graphene product, (iii) directly introducing the crude graphene into a high-pressure microfluidic device through a circulation pump, and stripping off to obtain graphene slurry, and (iv) subjecting the graphene slurry to physical sedimentation or centrifugal screening to obtain different grades and stable graphene pastes. USE - The method is useful for preparing graphene. ADVANTAGE - The method: utilizes pre-intercalation assistance and multi-stage stripping method for preparing graphene products, which can improves the production efficiency and product quality; does not cause pollution; and has controllable product cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene, prepared as mentioned above.
