Abstract

Versatile coatings based on the polymerization of aminomalonitrile (AMN) start to attract attention in the field of surface science owing to their biocompatibility and also in relation to the use of a precursor molecule being considered as a fundamental building block in prebiotic chemistry. As other emerging versatile coating methods, the polymerization of AMN produces not only coatings on almost all kinds of known materials but also the deposition of a useless precipitate in solution when AMN is dissolved at pH = 8.5. To circonvent this drawback, at least on conductive substrates, it is shown that AMN coatings can be obtained in a scan rate dependant manner on amorphous carbon electrodes by means of cyclic voltammetry at pH = 6.0 in conditions where AMN is stable in solution. The composition of the electrodeposited AMN coatings is compared with that of the solution processed coatings by means of X-ray photoelectron spectroscopy.
