Utilising its proprietary plasma surface engineered graphenes, Perpetuus Carbon Technologies has broken through the commercialisation barrier for graphenes.
Working with joint venture partner Gwent Electronics Group Ltd, two new graphene application enablers have been developed:
- A graphene enabled ink with a resistance below one ohm per square centimetre, making it the most conductive graphene enabled ink in the world. Perpetuus is offering immediate delivery of single kilogram batches for R&D and manufacturing optimisation. Tonne quantities will be available for customers who have completed production optimisation.
- A polymer coating that includes nano surface-engineered graphenes, which is a viable alternative to indium tin oxide (ITO). The Perpetuus material is an inexpensive, flexible, conductive coating that can be produced in commercial quantities, enabling the replacement of ITO.
Using graphene enabled inks, electronic circuitry and wiring can now be printed on flexible backgrounds, effectively changing many paradigms of the electronics industry and facilitating new products. Perpetuus graphene enabled inks are available in formulations for ink jet, flexographic printing and sensors technologies.
Nearly all touch-screen devices such as mobile phones and satnavs, use ITO - a rare, volatile, and geopolitically sensitive material - as their key transparent conductive component. However, ITO’s physical and geographical limitations mean the industry is hungry for a replacement material. ITO-enabled devices are limited by the brittle nature of indium which impedes the design flexibility necessary in 21st century devices.
Perpetuus’ ITO replacement has a bending radius of 5-10mm, which makes it ideal for current “roll up, roll out” manufacturing processes.
John Buckland, Chief Executive of Perpetuus, said, “Until now, industry has been unable to procure good quality functionalised graphenes in commercial quantities. The Perpetuus process provides a full range of dispersible, functionalised graphenes, carbon nanotubes and other nano device and component enabling materials in tonne quantities.”
