Preparation of Conductive Nanosilver Ink and its Application on RFID Tags

Abstract

The recent dramatic progress in the printed electronics and flexible electronics, due to the universality of the substrates including the foldable and stretchable substrates, has opened a new prospect in the field of future electronics. In this paper, silver nanospheres in large-scale are synthesized, the nanosilver ink with 63.88% silver content are prepared and a new type of highly conductive and far identify distance RFID tags are manufactured. Especially there are no resin and other additives containing in our conductive ink which satisfy the rheological characteristics and process of screen printing. The tags exhibit the best radiation performance own to there is no high temperature sintering in need. The surface resistance of the tags could be 80 mΩ/, and the identify distance reach to 6.0m. Keywords:silver nanoparticles, conductive ink, RFID tags

“…The AgNP ink has been extensively used for fabricating RFID tag sensors. [256][257][258] Copper nanoparticle-based RFID tag sensors Silver microake/nanoake-based conductive inks have been widely used in printed electronics. 259 However the increasing cost of silver metal has created a demand for less expensive, alternate conductive inks.…”

“…And an appropriate amount of ammonia was dropped into the reaction solution to control the PH in 10 or so, when the addition was complete, continue to keep stirring for 60 minutes. Finally, the reaction solution was centrifuged 5 times at a speed of 3000 r/min using an ultrasonic cell pulverizer for 10 minutes each, the supernatant was discarded and the remaining samples were dispersed and stored with ethanol [5].…”
