Bringing graphene and new materials to market
Remember the computer triode? Unless you’re an early-tech enthusiast, it’s unlikely. Used as switches in the first electronic computers, these vacuum tubes consumed a great deal of power. They were unreliable and upon the invention of silicon chips, were quickly replaced. A new material has the potential to shift entire industries. Here, Kari Hjelt, Head of Innovation of Graphene Flagship explains how graphene is set to do the same.
Graphene, a material that is just a one atom thick, has exceptional physical properties. The European Commission launched the Graphene Flagship in 2013 to facilitate the transition of graphene and related materials from academic laboratories to applications.
With a budget of €1bn and initial period of ten years, the Graphene Flagship is one of Europe's biggest research initiative, aiming not only to continue developing graphene in academic laboratories, but also spearheads efforts for the commercialisation of graphene, preparing for its widespread adoption in industry.
Over halfway through the ten-year project, the Graphene Flagship has successfully developed more than 25 commercial products, using the impressive conductivity, strength and flexibility of graphene to improve on the properties of previously used materials.
However, bringing a new material to market is not without its challenges.
Historically, it takes an average of 30 years to take a material from its invention into the commercial realm. Low cost aluminium, for instance, was first isolated in 1824, and for a while during the 19th century it was more expensive than gold, and considered as a very luxurious metal.
Aluminium wasn’t widely used until an affordable manufacture structure was set up in 1886, and it didn’t become popular until the early 1900s. Materials that also experienced similar time lags in their adoption include titanium, Teflon, Velcro and polycarbonate, a plastic material used in the manufacture of bulletproof glass.
Careful planning is essential in the phase when research and commercialisation start to overlap. Particularly due to the sharp contrast between the languages that are used in academia and industry. To ensure this process runs smoothly and successfully, a key driver is the establishment of efficient networks between both worlds. The Graphene Flagship has done this through a core consortium of over 150 academic and industrial groups. Around 50% of the current members are companies aiming to incorporate graphene into their products.
Thanks to this multidisciplinary network, the Graphene Flagship envisioned the Graphene Technology and Innovation Roadmap - an expected timeline for the adoption of graphene technologies. The roadmap focuses on fundamental industry areas, such as electronic devices, photonics, sensors, energy conversion, energy storage and biomedical devices.
On top of that, the Graphene Flagship has established two new services for the validation and standardisation of graphene and related materials, which will be of outstanding utility for industries looking into incorporating graphene into their products.
So far, the absence of accurate measurement protocols and the lack of standards have become a serious obstacle to the commercialisation of graphene and related materials. The Graphene Flagship enabled professional validation and standardisation processes - provided by national measurement institutes renowned for their excellence, integrity and impartiality - that will accelerate the technology development and transfer to industry.
The Graphene Flagship has also released an open access publication that gathers all the know-how in the manufacture of graphene and related materials acquired during years of basic research. Encompassing over 1,500 references and the knowledge of over 70 co-authors from the Graphene Flagship consortium, this handbook provides a single source of knowledge on graphene and other layered materials.
There were 124 years between the discovery of silicon in 1824, and the creation of the silicon chip in 1958. Now, arguably the most influential invention in computing so far, this chip technology is used in almost all modern products. Bringing a new material to market cannot be rushed, but when managed properly, can yield incredible results.
