The latest graphene ink news:
Researchers at Duke University have created transistors with three carbon-based inks. The all-carbon thin-film transistors were made using crystalline nanocellulose as a dielectric, carbon nanotubes as a semiconductor, graphene as a conductor and paper as a substrate. This type of component could assist in addressing the environmental problem of accumulation of electronics that are non-recyclable.
“Silicon-based computer components are probably never going away and we don’t expect easily recyclable electronics like ours to replace the technology and devices that are already widely used,” said Professor Aaron Franklin, an electrical engineer at Duke University. “But we hope that by creating new, fully recyclable, easily printed electronics and showing what they can do, that they might become widely used in future applications.”
Composed of aerogel graphene and two bio-inspired polymers, the novel material is reportedly capable of removing dyes, metals and organic solvents from drinking water with 100% efficiency. Unlike similar nanosheets, the scientists’ design is reusable, doesn’t leave residue and can be 3D printed into larger sizes. The team now plans to commercialize its design for industrial-scale deployment.
Advanced Material Development (AMD) has announced that it has signed a Letter of Intent with Marks and Spencer to further its work on the development of a green and sustainable RFID solution for the apparel and packaging industry.
AMD stated that it has made substantial progress on the use of its graphene based conductive ink technology to replace the aluminium and plastic materials that are incumbent in the ever-growing RFID applications industry. This has opened up opportunities in this sector for applications ranging from “green” to “flexible” solutions in a number of key markets.
Advanced Material Development (AMD) recently announced that it secured its first contract under the Defense Science and Technology Laboratory (DSTL) Weapons Sector Research Framework (WSRF), worth £125,000 (around USD$166,700).
The contract will fund the early development of AMD’s proprietary technology in carbon-based inks to improve protection systems for people and assets.
Haydale Graphene Industries has announced that its partner IRPC has now completed the development project with Haydale and started production of its new washable functionalized graphene-enhanced fabric mask.
IRPC has placed a follow-on order for 200 kilograms of Haydale’s bespoke ink, with further orders anticipated, the advanced materials group said. The face masks are currently being produced for use internally within the IRPC group, with a forecasted external order book for 2021.
