NOVELTY - Method for preparing graphene oxide-coated modified carbon black, involves using dispersant to modify carbon black to obtain modified carbon black, mixing graphene oxide and the modified carbon black in a solvent, and performing post-treatment to obtain the product. The dispersant comprises sodium dodecylbenzenesulfonate, APS, DL-602 and/or sodium dodecyl sulfate. USE - Method for preparing graphene oxide-coated modified carbon black (claimed). ADVANTAGE - The method provides the modified carbon black which significantly improves the dispersibility of carbon black, and improves the uniform color performance of the material.
