▎ 摘　　要

NOVELTY - A preparation method of bismuth ion mosaic graphene lattice slurry comprises (S1) adding natural flake graphite powder and chelated bismuth ion delamination agent to a reactor, mixing, adding buffer solution, carrying out the reaction, and after the reaction is completed, obtaining a delamination mixture, and (S2) adding an impacting agent to the delamination mixture obtained in step (S1) to carry out an impact reaction, and obtaining a bismuth ion-mosaic graphene lattice slurry after the reaction is completed. USE - The method is used for preparing bismuth ion mosaic graphene lattice slurry, which is used in any one of plastics, masks, clothing or ceramics to play a role of sterilization (claimed). ADVANTAGE - The bismuth ions themselves have the advantages of platinum and gold ions, and are the best material for anti-radiation and radiation protection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a bismuth ion mosaic graphene lattice slurry obtained by the preparation method.
