  • He notes that, since graphene's discovery, scientists working with natural graphite to produce graphene have used what is known as the Hummers method to turn graphene oxide into reduced graphene oxide (or rGO - a term which [Gordon Chiu] says has been incorrectly and interchangeably used with the term'graphene').

    "Because graphite has the same composition and arrangement as graphene, natural graphite is a popular and cost-effective precursor in the production of many graphene materials, including graphene nanoplatelets, reduced graphene oxide, and graphene oxide," Dr Elena Polakova, CEO of Graphene Laboratories told IM.

    "In order to restore some of graphene's natural properties - because graphene oxide is not conductive like graphene - we reduced the samples to create reduced graphene oxide. We then went a step further and converted the reduced graphene oxide into a paste with applications in conductive inks and coatings."
