Poly-Ink has developed two generations of conductive inks. The first, based on silver nanoparticles and a second, based on functionalized carbon nanotubes and conductive polymers. This ink combines the good processability of the conductive polymers with the high intrinsic conductivity of carbon nanotubes. Ink properties are compatible with inkjet and flexography process specificities. In 2014, Poly-ink propose actors of printed electronics, a third generation combining high conductivity, printability, productivity and lower costs.

Advantages
Contrary to traditional conductive inkjet inks based on metallic nanoparticles, the ink developed by Poly-Ink offers the advantage of not requiring a sintering step. This stage is often complicated involving high temperatures and induces a limitation regarding the substrate choice.
