ETFE RFID Tag with heteroatom-doped conductive carbon by screen print

Abstract

Abstract The Radio Frequency Identification (RFID) tag in Internet of Things (IoT) applications lacks high-performance substrates to meet the growing demand. Surprisingly, ethylene tetrafluoroethylene copolymer (ETFE) is the strongest and toughest fluoroplastic, which maintains good heat resistance and chemical resistance, possessing strong mechanical properties as well, suiting for RFID tag substrate materials. Herein, we have demonstrated a simple route for the made of RFID tag via self-made ETFE membrane and heteroatom-doped conductive carbon screen printing technology. The ETFE membrane that can be produced on a large scale by using extrusion calendaring method.The highly conductive heteroatom-doped conductive carbon is produced using solvothermal method. Using simple screen printing technology prepare the RFID tag. The ETFE membrane exhibits excellent mechanical properties, combined with the excellent conductivity of heteroatom-doped conductive carbon, providing a high-quality and high-performance substrate selection for RFID tag.
