▎ 摘  要

NOVELTY - Preparing graphene, comprises (i) mixing stripping auxiliary agent and organic solvent in a ratio of 1:8-12 to obtain dispersant, (ii) adding natural graphite powder into the dispersant, and stirring at a speed of 1200-2000 revolutions/minute for 10-15 minutes using a stirrer, (iii) subjecting the stirred solution to at least one high pressure homogenization treatment under a pressure of 1500-1600 bar, and (iv) reacting at 200-230 for 2-3 hours, and naturally cooling to obtain final product. USE - The method is useful for preparing graphene. ADVANTAGE - The method: shortens overall processing time by 40-60%; reduces overall production cost by 30-40%; and improves production efficiency and competitiveness.
