▎ 摘 要
NOVELTY - Preparing graphene composite conductive paste involves carrying out the first high-speed shearing dispersion of the dispersant and binder, adding highly conductive graphene and organic solvent, and carrying out grinding and ultrasonic dispersion to obtain graphene slurry. The second high-speed shearing dispersion of the dispersant and binder is carried out, carbon nanotubes and organic solvent is added, and then the second grinding is carried out to obtain a carbon nanotube slurry. The graphene slurry and the carbon nanotube slurry are mixed to obtain a graphene composite conductive slurry. The graphene composite conductive paste includes a dispersant and a binder. USE - Method for preparing graphene composite conductive paste. ADVANTAGE - The method achieves better electron and ion transmission effects, and displays the better performance of graphene and carbon nanotubes.
