Functionalized Multiwalled Carbon Nanotubes

Functionalized Multiwalled Carbon Nanotubes Functionalized Multiwalled Carbon Nanotubes (MWCNTs) are made of many graphene layers and the diameter can be up to 100 nm. Two main models describe MWCNTs: (i) the Russian doll model or coaxial cylindrically curved model in which many graphene layers are rolled up and arranged in a cylindrical fashion, and (ii) the parchment model in which a single graphene layer is scrolled as a parchment (Figure 5a and c respectively). A further evolution of the coaxial cylindrically curved model is the coaxial cylindrically poligonized. The electronic structure of a MWCNT is considered as the sum of the electronic structures of the constituent nanotubes. Thereby, we state that in the limit of the large nanotube diameter, all […]
