Towards Formulating Conductive Nickel Ink for Flexography Printing

Printing methods and conductive inks have brought electronic manufacturing to a new level by enabling production of thin, light-weight and flexible components at high speed, low cost and low waste. The printed electronic market is massive, yet the developments and varieties in ink formulation is very limited. This paper reports an alternative conductive ink for flexography printing. In the formulation, metal nickel sphere particles are mixed with different latexes and acrylic resins in water and ammonia. The optimum photonic curing condition is presented along with electrical response of the ink films.
