NOVELTY - Preparing modified graphene slurry involves grinding raw materials in system to obtain primary grinding slurry, circularly grinding grinding slurry in circulation system to obtain secondary grinding slurry. The secondary grinding slurry is added into the grinding cycle and ground multiple times to obtain modified graphene slurry, where raw material comprises expanded graphite, surface active agent and solvent. USE - Method for preparing modified graphene slurry (claimed). ADVANTAGE - The method enables to prepare modified graphene slurry in simple manner which does not generate has impurity. It is more stable, not easy to reunite, and suitable for transporting and storing for long time.
