of CNTs can be reduced (Monthioux et al., 2001). Moreover, certain highly
reactive chemical products also involve harsh conditions causing detri-
mental damage to the tips and sidewalls of CNTs, which decreases their
stability and can cut them into short pieces (Liu et al., 1998). In addition, the
solvent functionalization process generally requires time-consuming multi-
step reactions. Finally, the use of organic solvent pollutes and is difficult to
upgrade for industrial processes.
