CVD Synthesis of Hierarchical 3D MWCNT/Carbon-Fiber Nanostructures
Figure 2
TEM images of Showa Denko fibers and the produced secondary tubes, grown
with Ni and for 20 minutes at C with optimal gas composition: (a)
VGCFs and secondary MWCNTs. The inset is a close-up of the end of a secondary MWCNT,
showing an encapsulated Ni catalyst particle.
(b) Two different secondary MWCNTs. Imaged using Philips CM200 FEG TEM.
