FIG. 1.

Transmission electron microscope micrographs showing: (a) The regular wall structure of an AD-grown MWCNT and (b) the more irregular wall structure of a CVD-grown MWCNT.

FIG. 2.

(a) MWCNTs partially embedded in epoxy glue were tested in tension until (b) fracture of the nanotube occurred (fracture ends indicated by arrows). The ends of the nanotube exhibited either (c) a clear break or (d) a thinning of the nanotube diameter over a small length . The total cantilever deflection used to calculate fracture force was measured (e) from the double black arrow.

FIG. 3.

Weibull plot for the tensile strength of CVD-grown MWCNTs. Dotted lines show the stress levels where 25% and 75% of nanotubes fail.
