The chemical modification of CNTs can be endohedral (inside the cavity of the tube) or exohedral [42]. There are some examples in the literature that have demonstrated the filling of CNTs with fullerenes, biomolecules (proteins, DNA), metals and oxides that have been driven inside by capillary pressure [39, 42, 72-78]. However, in this section we will focus on exohedral functionalization, taking place just at the external walls of the tubes. Both covalent (chemical-bond formation) and noncovalent (physiadsorption) functionlizations can be carried out. In the following...
