LayerOne and SINTEF secure funding from The Norwegian Research Council for the development of innovative, scalable and sustainable conductive inks based on reduced graphene oxide (rGO). The rGO-based inks promise improved electrical conductivity and stability surpassing traditional carbon-based inks and offering a less toxic and more cost-effective alternative to metal-based inks.
The research project is a result of LayerOne’s recent breakthrough in developing a new grade of rGO with an electrical conductivity two orders of magnitude greater than standard rGO grades. In the project LayerOne will supply the advanced rGO materials while SINTEF will leverage and build on its experience from recently concluded projects on printed electronics to develop the new conductive inks.
The project, valued at 18 million NOK, has been awarded 9 million NOK in funding from the Norwegian Research Council. The conductive ink market was estimated at 3.0 billion $ US in 2020 and is expected to reach 3.7 billion $ US by 2025*.
According to Christian Dethloff, CEO of LayerOne, this innovative rGO-based technology is expected to have positive impact on various electronic equipment such as RFID tags, sensors, circuits, and even high-tech clothing with integrated electronics.
According to the company's research, traditional carbon-based inks often offer low electrical conductivity and are low-cost, while metal-based inks provide better performance but at a higher cost. However, there is still a significant gap in terms of both performance and cost between these two technologies. LayerOne's graphene-based conductive inks address this gap by providing improved conductivity compared to traditional carbon-based inks at a reasonable additional cost, making them a cost-effective alternative to metal inks and a premium product compared to carbon-based inks.
