Different levels of structure and chemistry in carbon black: (a) TEM image of N660 carbon black at the indicated magnification; (b) schematic of a primary particle (cut in half to show the internal structure) that is composed of stacks of graphene sheets (adapted from Heidenreich et al. [48]); and (c) depiction of the different chemical groups on a graphene sheet in CB along with possible defects in the sheet. The various functional groups and defects are described in the discussion text.
