▎ 摘 要
NOVELTY - Pre-dispersing graphene slurry comprises (i) weighing graphene raw material, surfactant, dispersing agent and solvent, (ii) weighing the graphene raw materials, the dispersing modifier, and the solvent in a mass ratio of 10-15, adjusting the stirring speed to 1000-1200 revolutions/minute, increasing the rotating speed along with the adding amount until the stirring is uniform, (iii) weighing modifier with a weight ratio of 0.5-1, setting the stirring rate to 1000 revolutions/minutes, and uniformly stirring until the mixing is complete, and (iv) placing the graphene residue into an ultrasonic wave instrument for ultrasonic vibration to obtain a final graphene residue. USE - The method is useful for pre-dispersing graphene slurry. ADVANTAGE - The method overcomes van der Waals force and ππ interaction, avoids graphene agglomeration, improves dispersion effect, and can be modified according to needs, and the graphene slurry is not restricted.
