Figure 7
TEM images of MAed graphite powders for 150 h after one-step and two-step annealing with different morphologies: (a) springlike MWCNFs encapsulated with carbon nanotubes (two-step), (b) individual MWCNFs (two-step), (c) MWCNTs with an ultrahigh crystallinity structure (one-step), and (d) individual MWCNTs with narrow channels (one-step).
