Breakthough graphene inks to accelerate graphene applications

Haydale, a leader in facilitating the commercial application of graphenes announces that with its development partner, Gwent Electronic Materials ("GEM"), it has developed graphene based inks with properties that now quickly enable its customers to use graphene in a wide range of applications. This breakthrough has been possible due to the ability of Haydale to supply quality graphenes in commercial quantities at a viable price.
These new graphene inks enable the commercialisation in the near future of smart packaging, printed batteries, electrochemical sensors, flexible displays and potentially touch screens. The inks are launched today at the Graphene Commercialisation & Applications Summit in London.
Haydale's graphene based inks were first announced at the Printed Electronics USA conference in December 2012, since then Haydale has been working in close collaboration with specialist ink manufacturer GEM. This has resulted in the rapid improvement of the ink formulations, and enhancement of conductivity performance.
Martin Williams, Haydale Technical Manager and co inventor of the patented plasma process said: "The development of graphene inks with conductivity better than normal carbon based inks is a major step forward in enabling a myriad of commercial applications of graphenes to take place now. Applications that were previously only thought possible with 'yet to be developed and commercialised' CVD processes are now immediately accessible with our HDPlas graphene inks."
Haydale's metal free HDPlasTM Graphene Ink Sc213 is specifically formulated for screen-printing applications. It has been optimised for ideal viscosity and solid contents ensuring excellent coverage and exceptional conductivity. The inks are fully customisable and can be modified with development partners for specific requirements including:
  • Plastic Electronics
  • Flexible Displays
  • Liquid Crystal Displays
  • Printed Circuit Boards
  • Sensors
  • Catalytic Devices
  • E-Paper
  • OLED Devices
  • Transparent Electrodes
  • Thin Film Photovoltaics
  • Electrochemical Devices
Sample batches from 100gms to 5kg are available now. Technical Data for the SC213 Ink and prices can be found at: External Link
GEM's Technical Director Robin Pittson said:
"Haydale's HDPlasTM graphene nano-materials have proved to be ideally suited for ink formulation. The consistent high quality of the material combined with the range of surface functionalities and the ease of dispersion into the formulated ink base has significantly cut development time. We are very excited to be working with this new material and the Haydale technical staff."Ray Gibbs, Commercial Director at Haydale added:"Graphene has been described as a zero billion dollar market, mainly because many of the applications that have been discussed are dependent on production technologies that are yet to be developed commercially. The immediate use of HDPlasTM materials now in place of other future possible graphene offerings allows many of the key applications to be realised in the near term.At Haydale we have been working on the ability to commercialise graphene technology for 2 years and today is a significant milestone for us. The key to having commercial products using graphenes is the ability to homogeneously disperse it into the host material. We are especially pleased that the performance can be achieved with no metal additives. Today, our annual production capability of graphene nano materials is 1 tonne, but is scheduled to increase substantially this year in response to known demand.The ability to address the conductive ink market now, with a new graphene product has been achieved through close collaboration with a specialist ink manufacturer. It is exactly that type of association we are seeking across a range of manufacturing sectors where our graphene technology can be applied using our patented technology."
