Copper based inks have been gaining interest as a potentially cheaper alternative for the conventional, market ready conductive silver inks. However, most of the current copper inks in the market have the tendency to oxidize under room conditions, leading to performance issues and thereby limiting their adoption.
This technology presents a range of conductive materials, specifically copper inks, targeted at the flexible printed hybrid electronics sector. These functional materials are specifically designed to be printable, cured at low temperature and flexible, making them ideal for printed electronics. Furthermore, the inks have been formulated to be extremely stable under ambient conditions, providing several advantages over the existing state of the art.
The technology presents two variations of copper inks: copper complex ink, and copper particle ink.
The described technology composes of the following features:
This technology is applicable (but not limited) to printed electronics in general. The inks enable the printing of conductive traces on both flexible and rigid substrates. Examples of these are:
