The latest graphene ink news:
Haydale has announced that, following its announcement of positive prototype testing on 3rd March 2020, its range of advanced wearable technology - integrated into garments for elite athletes - was used in Tokyo by British athletes, including top medal winning athletes.
The garments generate heat using Haydale's printed functionalized graphene ink and incorporate electronic circuitry to produce temperature regulated panels. The plan is to use them at future international competitions, and subsequently to make them available commercially to other professional sports.
Researchers from Kansas State University, led by Suprem Das, assistant professor of industrial and manufacturing systems engineering, in collaboration with Christopher Sorensen, university distinguished professor of physics, have shown potential ways to manufacture graphene-based nano-inks for additive manufacturing of supercapacitors in the form of flexible and printable electronics.
The team’s work could be adapted to integrate supercapacitors to overcome the slow-charging processes of batteries. Furthermore, Das has been developing additive manufacturing of small supercapacitors — called micro-supercapacitors — so that one day they could be used for wafer-scale integration in silicon processing.
Advanced Material Development (AMD) will fund £2 million of research by the University of Sussex to develop nanomaterial technologies for environmentally sustainable uses. This funding will pay for five researchers to work on developments for the next three years.
Professor Alan Dalton, who leads the university’s Materials Physics Group and is a and co-founder of AMD, said: “We’re on the cusp of taking a number of our inventions out of the lab and to market, and this significant new boost from AMD means we can recruit the team we need to make the next step... The company has exciting collaborations with Marks and Spencer, Honeywell and many other global companies lined up. The potential applications for nanomaterial inks are boundless.”
Under a binding memorandum of understanding (MoU), AMD will provide expertise in the design and development of functional nanomaterials and hierarchical assembly of material systems, while First Graphene delivers capabilities in the development, manufacture and supply of its graphene nanoplatelets, branded PureGraph.
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.”
