Benefits of technology

This patented technology improves on existing methods for creating electrically conductive circuits through adding tiny metal particles called Silver NPs (Silvernanic Pigments) onto paper or plastic films during printing processes. These Metal Nanopartains have very fine sizes which are easy to mix into solutions without losing its effectiveness over time. By doing this, it saves money while still producing effective devices like radio frequency identification tags. Additionally, these techniques allow for more flexibility when customizing electronics products' designs based upon specific requirements such as impedance matching, inductor values, etc., resulting in improved performance and functionality within certain applications.

Problems solved by technology

This patented technical solution describes different ways how to make better quality electronics tags without generating excess material during their fabrications or requiring expensive processes like etched/elecrochromic plasma techniques. Additionally, there are also various types of conductor materials available but they have issues associated with producing these items at reasonable prices due to poor performance compared to traditional metal wire coil antennas made from metals. Therefore, we propose developing new type of conductors called gravured-Printed (CP) instead of conventional ones, allowing us to create smaller devices while maintaining excellent security fidelities against counterfeiters.

Abstract

The invention discloses nano conductive ink. The nano conductive ink is prepared from the following components: 60-80 parts of conductive metallic packing, 0.1-5 parts of silver nanoparticles 2-50nm in particle size, 1-12 parts of high molecular organic resin, 0.5-5 parts of an adhesion accelerant, 0.1-2 parts of a flatting agent, 0.1-2 parts of an antifoaming agent and 10-25 parts of an organic solvent. The invention also discloses a preparation method of the nano conductive ink, an RFID antenna of the nano conductive ink, and a preparation method of an RFID electronic tag. The nano conductive ink has the beneficial effects that the RFID antenna printed by using the nano conductive ink is ultrathin and uniform in thickness and has good conductivity and adhesive force, also consumption ofthe conductive ink can be reduced by reducing the thickness of the RFID antenna, and the cost is greatly reduced.
