Abstract

The invention relates to the technical field of graphene and discloses a graphene-based RFID (radio frequency identification) antenna. The graphene-based RFID antenna comprises the following raw materials: 100-150 parts of graphene, 20-40 parts of epoxy resin, 10-20 parts of alcohol, 10-20 parts of chain extender, 20-30 parts of gel, 30-50 parts of silver powder, 50-70 parts of printing ink and 110-130 parts of paper. The printing method of the graphene-based RFID antenna comprises the steps of putting 20-30 parts of gel and 20-40 parts of epoxy resin in a container, heating to 120 DEG C, performing stirring for 3h at a frequency of 50 revolutions per minute to prepare an insulation sealant, coating the surface of a crude graphene-based RFID antenna prepared in step 2 with the insulation sealant uniformly, putting the coated crude graphene-based RFID antenna in a ventilated place for natural drying, taking out the crude graphene-based RFID antenna after 24h to form the graphene-based RFID antenna. The graphene-based RFID antenna coated with the insulation sealant isolates oxygen; quick oxidation does not occur; a service life of the graphene-based RFID antenna is greatly prolonged;the worries of a user are removed; and the use of the user is facilitated.
