South Korea developed successful nano conductive ink

ABC nanotechnology company in Daejeon, South Korea, has successfully developed a nano-conductive ink that can be applied to rapidly developing wireless RFID tags, printed circuit boards (PCBs), and flexible printed circuit boards (FPCBs). Can be used to print electromagnetic shielding materials.

ABC Nanotechnology uses nanosilver as the main body of conductive ink. The finished conductive ink is a colloid, the content of solid matter is less than 30%, and the metallic silver is evenly dispersed in the colloid with a diameter of less than 25 nanometers, so that the ink has an ideal resistivity. Experiments have shown that conductive ink can not only print circuit boards at the frequency of RFID chip use, but also has the same performance as traditional copper coils. The use of conductive ink can not only print the RFID circuit, but also print the antenna at the same time, which is faster and cheaper than conventional printed foil or etching circuit manufacturing processes.
