NOVELTY - Conductive ink comprises 20-40 pts. wt. graphene nanosheets, 10-40 pts. wt. metal filler, 2-10 pts. wt. polymerized monomer, 1-5 pts. wt. photoinitiator, 1-5 pts. wt. dispersant, 1-5 pts. wt. coupling agent and 30-60 pts. wt. solvent. USE - Conductive ink. ADVANTAGE - The conductive ink has high conductivity and stability, RFID electronic tags are resistant to high temperature water washing, low manufacturing cost and high production efficiency. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing conductive ink, which involves mixing raw materials and stirring to uniformly disperse the graphene nanosheets and the metal filler in a solvent system and grinding and performing homogeneous treatment; (2) an Radio-frequency identification (RFID) antenna, which used conductive ink and the square resistance of the RFID antenna is 0.5-10 ohm; (3) a method for manufacturing an RFID antenna, which involves printing conductive ink on a substrate to obtain an antenna pattern and irradiating antenna pattern with pulsed strong light, and performing photo-curing process to obtain an RFID antenna; (4) an RFID electronic tag, which comprises Inlay layer composed of a chip and an RFID antenna, where RFID antenna is attached to one side of the chip, and both sides of the Inlay layer are sequentially provided with a hot melt adhesive layer and a base layer; and (5) a method for preparing an RFID electronic tag, which involves forming Inlay layer by attaching the RFID antenna to one side of the chip, and forming an Inlay layer on each side of the chip, arranging hot melt adhesive layers on both sides of the layer, and fusing base layer.
