▎ 摘 要
NOVELTY - Preparing graphene slurry comprises (i) subjecting expandable graphite to high temperature expansion, separating material gas, paving and rolling into paper to obtain graphite worm, (ii) pulverizing obtained graphite paper to obtain graphite powder having particle size of 100-300 mu m, (iii) further pulverizing obtained graphite powder to obtain graphite fine powder having particle size of less than or equal to 5 mu m, (iv) mixing graphite powder with solvent, stirring evenly, treating by high-speed shearing machine and performing ultrasonic treatment to obtain final product. USE - The method is useful for preparing graphene slurry. ADVANTAGE - The method: expands high-magnification expandable graphite and rolls it into paper to increase unit volume density; performs subsequent preparation and sufficient stripping, and removes exhaust gas and impurities.
