Typical defects along a single-wall CNT: (A) five- and seven-
membered rings forming a bend in the tube; (B) dangling bonds; (C)
hole in the carbon framework; and (D) open end of CNT terminated
with -COOH groups (Hirsch, 2002).
the reaction with diamines such as triethylenetetramine (Gojny et al., 2003),
ethylenediamine (Meng et al., 2008) or 1,6-hexamethylenediamine (Li et al.,
2007). Another approach involves the reduction of the carboxyl groups to
hydroxyls, followed by transformation into amino groups via phthalimide
coupling and hydrolysis (Ramanathan et al., 2005). Gromov et al. (2005)
have developed two other approaches, using amino-decarboxylation
