Edge-carboxylated graphene nanoflakes from nitric acid oxidised arc-discharge material
Christoph G. Salzmann, Valeria Nicolosi and Malcolm L. H. Green
Graphene nanoflakes (GNFs) with average diameters of
30 nm have been prepared by a single-step oxidation procedure using single-wall carbon nanotube arc-discharge material and nitric acid. The GNFs are predominately single sheets containing a small number of internal defects. The edges are decorated with primarily carboxylic acid groups which allow facile chemical functionalisation and cross-linking of the fragments using multivalent cations.
