Chemical synthesis of graphene nanoribbons Conference Paper uri icon


  • The importance of graphene as a new material is due to its electrical and mechanical properties, good conductivity, excellent heat dissipation, flexibility and transparency. Therefore it offers a good suitable material to the actual demands on new technologies. Graphene nanoribbons (GNRs) are obtained by cutting a graphene sheet into quasi-one dimensional infinite ribbons. GNRs are materials showing different properties compared with others carbon nanostructures because they can act from semiconductors to semimetals as a function of their width. In this work, we describe an oxidative method, using only potassium permanganate (KMnC4) as the oxidant agent, for the synthesis of GNRs coming from the unzipping of multi-walled carbon nanotubes, which are synthesized using a mixture of xylene with an alcohol as the carbon source and ferrocene as the catalyst.
