The Holst Centre and NeoDec to partner on inks for flexible electronics

The Holst Centre and NeoDec will partner on metallic inks for flexible electronics. NeoDec's conductive ink technology is a complementary technology to the competences of Holst Centre and its industrial
partners and opens new routes to enable roll-to-roll manufacturing of flexible electronic devices such as OLED lighting foils. The partnership will initially run for 2 years, and NeoDec's technology will be further developed within the Holst Centre.

For the anticipated flexible electronics applications, like shunt lines for OLED and current collectors for thin-film photovoltaics, commonly used metallic inks require temperature-based post-curing. This to enhance the conductivity of the printed metallic structures to the required level. In particular in case of foil based electronics, the post-curing temperature is limited by the allowable processing
temperature of the polymer substrates.

The patented NeoDec technology was developed at the Eindhoven University, and it enables cost-effective patterning of metallic structures based on their proprietary process. A unique feature of this technology is the room-temperature post-curing for obtaining the highly conductive
metallic structures. The NeoDec process is compatible with inkjet and rotary screen printing, making it very useful for high-throughput roll-to-roll manufacturing of plastic electronics.
