Metal-based nanoparticles and carbon black particles have been used previously as the conducting phase in inks for the printing market due to their high conductivity. Polymeric conductive materials can alleviate the high-cost burden of metals but have had significant problems with solubility and some resulting in lower than desirable conductivities. The technology discussed herein solves both of these barriers.
The electrochemical ink in this conducting polymer colloidal nanocomposite invention includes a dispersion of colloidal nanocomposite particles in liquid carrier. The ink can utilize any carrier liquid. The shell is formed of conducting polymer and the core material can be selected depending on the required characteristics of the ink.
Applications:
· Printing processes: Lithography, flexography, screen, and inkjet printing
· Photovoltaics
· Radio Frequency Identification (RFID) components
· Sensors
· Memory devices
Benefits:
· Environmentally-friendly benign solvents (water, alcohols)
· The conducting polymer inks can be printed at high-speeds and high-volume
· Can be printed on a variety of substrates
· Low Cost
