The issue of how to separate the individual layers into the single molecule thickness sheets seems to be on the way to being resolved with the latest research collaboration between US and Japanese scientists identifying non-oxidative intercalation molecules in a group of acids.
It was also reported recently that specialist producers of graphene are slowly moving towards commercial products, however issues remain with the matching of properties required.
In the Graphene SIG we are focused on just this issue, looking at all the likely application areas and researching the property requirements, as all are likely to need different properties in the end product.
Should these be identified there will remain other issues, not least of which will be a transition of manufacturing processes from one (current) product to a new material with likely different manufacturing equipment requirements. Also the question of standards and longevity will have to be addressed.
All these challenges mean that graphene has to be a wonder material that can deliver something that the current materials cannot, as almost all applications demand a risk averse development approach with incremental improvement in place of more radical change.
