CNTs “Taunit” and Synthesis Thereof

 

 

These products represent multi-walled carbon nanotubes – nanosized, quasi-one-dimensional, filamentous polycrystalline graphite cylindrical formations with internal channels.

 

Their characteristics are given in Table 2, and SEM images of their surfaces are presented in Fig.
