Figure 2
NP2 sample. (a) TEM image of unzipped SWCNTs after sulfonitric mixture treatment at room temperature, and (b) corresponding ED pattern with experimental d spacings and with Miller indexes of hexagonal/orthorhombic phases. (c) Bright field TEM image of typical flakes, including an ordered stacked assembly of graphene layers, reported at higher magnification in (d). (e) Electron diffraction pattern taken from the region shown in image (d). (f) Theoretical electron diffraction pattern in reciprocal space and (g) corresponding structural model of the orthorhombic graphite phase with the electron beam along the [[\overline 6\overline 5]5] zone axis in real space. (h) Perspective structural model of bilayer graphite stacking along the crystallographic c axis.
