▎ 摘　　要

NOVELTY - Preparing high-conductivity ink comprises mixing graphene powder with water, peeling and dispersing by a homogenizer, obtaining aqueous dispersion of graphene, concentrating, preparing the first concentrated slurry with mass content of graphite alkene of 5-15%; adding organic solvent dissolved with water in the first concentrated slurry; mixing; evaporating part of water and organic solvent dissolved with water in evaporation way; preparing the second concentrated slurry with mass content of more than 50% of graphene; adding the remaining raw material to the second concentrated slurry, and mixing to prepare the high conductive ink for graphene-based RFID electronic label; where the raw material of the ink comprises a conductive agent, a resin matrix and a solvent, the conductive agent is a combination of graphene powder or graphene powder and other conductive agent, where the solvent comprises water; and organic solvent miscible with water. USE - The high-conductivity ink is useful for graphene-based radio-frequency identification (RFID) electronic tag. ADVANTAGE - The ink has high quality content of graphene, good dispersion, greatly reduces the amount of organic solvent, reduces the amount of precious metal, ensures specific conductivity under the premise, and realizes the printing of RFID antenna. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) high-conductivity ink for graphene-based radio-frequency identification (RFID) electronic tag; and (2) an RFID electronic tag, comprising an RFID antenna, where the radio-frequency identification antenna is made by printing the graphene-based radio-frequency identification electronic tag with high-conductivity ink.
