▎ 摘　　要

NOVELTY - Graphene complex conductive ink comprises 30-100 pts. wt. graphene slurry, and 5-20 pts. wt. metal-coated carbon black nanoparticles. In the graphene slurry, the mass fraction of graphene is 5-20 wt.% in the metal-coated carbon black nanoparticles. The metal includes gold, silver, copper, nickel, and/or cobalt. USE - Used as graphene complex conductive ink. ADVANTAGE - The method: prevents graphene from being stacked again; reduces the contact resistance between graphene sheets and carbon black particles; improves the conductivity and conductivity of graphene complex inks stability; improves the comprehensive performance of graphene complex ink. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the ink comprising adding the graphene, dispersant, and auxiliary agent to the solvent for dispersion, and homogenizing treatment to obtain the graphene slurry, mixing the metal-coated carbon black nanoparticles with the graphene slurry, and mechanically dispersing them at a rotation speed of 2000-5000 rotations/minute (rpm) for 3-5 hours, where, the metal-coated carbon black nanoparticles are prepared by one of a chemical deposition method, an electrodeposition method, and a vacuum sputtering method, preferably, the metal-coated carbon black nanoparticles are prepared by the following method the metal salt-containing plating solution is reacted with carbon black in the presence of a reducing agent; and (2) RFID antenna, comprises a conductive ink layer and a plastic substrate, the conductive ink layer covering the surface of the plastic substrate, where the conductive ink layer is obtained by printing the ink.
