Extremely fine nanopowders of pristine graphene nanoplatelets. The pristine graphene nanoplatelets have a lateral dimension of a few micrometres and a thickness of a few nanometres.
The nanoplatelets are weakly aggregated by van der Waals forces, exhibiting an apparent density of around 60 g/L. Pure G+ nanopowders are produced without the use of any surfactants and they are not subjected to any oxidising steps. They can easily be dispersed in practically any kind of media, from solvents to polymeric matrices, giving the ability to match the required solid content.
