Problems solved by technology

Although these preparation methods have their own advantages and disadvantages, in the process, prepared products and subsequent applications, graphene and water or other dispersion media are often required to form a slurry, and the characteristics of nanomaterials that are easy to agglomerate will affect the production process. impede the realization

[0004] The more commonly used dispersion methods are to introduce dispersant, apply mechanical shear force or ultrasonic treatment, but the addition of dispersant undoubtedly introduces more impurities to high-quality graphene slurry, which does not meet its technical requirements; Although ultrasonic treatment has a good dispersion effect, it is difficult to achieve continuous industrial
