Printed electronic circuits will significantly decrease the cost of radio frequency identification devices (RFID). Since printed circuits are relatively inexpensive, Das and Harrop (1) estimate that printed devices can capture over 60% of the RFID market by 2017. Silver is currently the conductive material used in these printed circuits. Possible printing processes include either silver flake or silver nanoparticles with solvent based, water based or UV curable binders. This research studies the fate of flaked or nano particle silver printed with the different binders. Methods for analyzing silver from a paper sample were developed. It was found that the silver separates from the fibers during repulping and becomes part of the fine fraction.
