▎ 摘　　要

NOVELTY - Graphene conductive ink comprises ink solvent, and graphene spun fibers dispersed in the ink solvent, and a dispersant is distributed on the surface of the graphene spun fibers. The addition amount of the graphene spun fiber in the conductive ink is 50 wt.%to 65 wt. wt.%. USE - Graphene conductive ink for RFID electronic tags. ADVANTAGE - The graphene conductive ink has improved conductive effect, improved anti-calendering deformation resistance, and with a specific ink solvent, the adhesion performance on the substrate after curing is also better. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the graphene conductive ink, which involves using electrospinning to make graphene spinning fiber from spinning solution containing graphene, immersing the graphene spun fiber in the dispersing agent solution and stirring, so that the graphene spun fiber is distributed with the dispersing agent on the surface and taking out graphene spun fiber with the dispersant distributed on the surface, vacuum drying, and dispersing in the ink solvent to obtain the graphene conductive ink.
