A combined two-step method of preparing PPy nanowires was reported, consisting of (i) electrochemical grafting of a thin polyacrylate film at a carbon electrode and (ii) electropolymerization of pyrrole, resulting in polypyrrole wires with diameter 600 nm and length 300 xm, growing through the pores of a polyacrylate film [244].

The electrochemical grafting of aryl groups from aryldiazonium precursors has been a very popular field of research in the past two decades [86,186]. Aryldiazonium salts are conveniently prepared by reaction of an arylamine with the nitrite ion in acidic aqueous medium at ca. 0 °C temperature [187] ... 

The covalent attachment of MN4-MC on the surface of CNTs has been another way of combining macrocyclic complexes and carbon supports to fabricate functional hybrid materials. Coates et al. [56] described the chemical modification of SWCNTs after their adsorption on GC electrode. The procedure consisted first in the electrochemical grafting of 4-azido benzenediazoium salt on the surface of CNTs, followed by a reaction with ethylpyridine through click chemistry. Finally, the attachment of a FePc was carried out by axial bonding to the pyridine group. An illustration of these steps can be seen in Fig. 9. The sensor was applied in the electrocatalytic detection of hydrazine, with a ten times improvement of the limit of detection over the surface without the CNTs.
