CNTs “Taunit” and Synthesis Thereof
- Category: Products
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.
Principal characteristics of the industrially produced “Taunit” nanoproducts.
