Technology Opportunities

Novel formulation enables printing on low-cost plastic substrates

Highlights

• Enables the printing of low-cost conductive patterns.
• Low decomposition temperature – enables printing on temperature-sensitive, low-cost plastic substrates
• Highly stable ink – no aggregation and no oxidation problems
• Simple process and environment friendly solvents

Our Innovation

Currently used conductive inks are very expensive (silver based inks), are not stable in air (copper based inks) and require high sintering temperature. Here we present new copper inks with high metal load and low decomposition temperature (<150o C), which enable the printing of low-cost conductive patterns on sensitive plastic substrates.

Key Features

• Low-cost copper-based inks
• No aggregation and no oxidation problems
• Enables printing of conductive patterns on low-cost heat-sensitive substrates such as PET
• Can be tailored for ink-jet, flexo and screen printing

Development Milestones

The next step in the development of the technology is its implementation in the production process of a company that currently produces conductive inks.

The Opportunity

• The total market for printed, organic, and flexible electronics is projected to grow from more than $16 billion in 2013 to $76.8 billion in the next 10 years (IDTechEx.)
• Perfect for various applications including RFID-tags, solar cells, sensors and electrodes
• Low-cost process
