Is Graphene ending the promises for Carbon Nanotubes?

Let me start with what’s in the background, and why I think this is a valid and potentially a highly influential technological issue these days. This month it rather surprisingly hit the news that three years after Bayer MaterialScience (a leader in material solutions) invested 22 million euros into a carbon nanotube (CNT) production facility which had a very promising future, then they decided to close it down because of lacking groundbreaking applications in sight.1 In other words they trusted, somewhat blindly, that the growth rate of worldwide CNT demand could increase up to the level of the production capacity. Well, as you’d guess this is still very much unbalanced toward the latter. Or, is it the success of the Nobel Prize-winning big brother – graphene – that is shaking the whole CNT empire?

Graphene, the next disruptive innovation?

If you reading this then none of the cataclysmic events predicted by Mayans for December 21st, occurred. Hooray, but let’s hope it’s not because they are late! Anyway, I say let’s celebrate this with looking back at 2012 from a materials scientist point of view, and spend some time on what I think was arguably the “celeb” material of the year, graphene.

Luckily and not surprisingly 2012 in science (UN International Year of Sustainable Energy for All) involved many significant breakthroughs and surprising turns of events, including scientists from CERN reporting the first indirect evidence supporting the existence of the Higgs boson; IBM engineers developing the first working 9 nm transistor using nanotubes as an alternative technology to the silicon as well as making the first steps towards the commercializing the production; demonstrating the storage of a single bit on just a dozen super-cooled iron atoms instead of a million, so making way to the future ultra-high-density storage media; Intel commercializing the world’s first 22 nm microchip family showing greatly increased computational power and energy efficiency; and researchers from IBM (again!) revealing a new lithium-air battery with far greater energy density than the currently used lithium-ion batteries which could be utilized in the production of electric vehicles.
