▎ 摘 要
NOVELTY - A uniform graphene dispersion is prepared by mixing (g/l) surfactant aqueous solution (0.2-20) and raw graphite powder (1-100) to obtain a suspension, stirring the suspension at a speed of 50-300 revolutions/minute (rpm), heating at 100-300 degrees C and a pressure of 0.1-8.6 MPa for 5-24 hours to obtain a slurry, centrifuging at a speed of 1000-2000 rpm for 15-45 minutes, and filtering. USE - Method of preparing uniform graphene dispersion. ADVANTAGE - The method is low cost, recycles materials, does not discharge waste gas, utilizes non-corrosive and non-toxic materials, does not damage native conjugated structure of graphene, can be applied to industrial production, and prepares product having excellent dispersity and stability. DESCRIPTION OF DRAWING(S) - The drawing is a flow chart of a method of preparing a uniform graphene dispersion (Drawing includes non-English language text).
