AND METAL CORROSION PROTECTION
Synthesis of metal clusters and nanoparticles in
polymeric matrices constitutes one of evolving areas
in which metal-containing systems are formed .
Polymeric nanocomposites containing metallic silver(0)
possess antimicrobial and antiviral properties [2–6].
Of particular importance in the formation of
silver-containing composite coatings is the nature and
nanostabilizing efﬁ ciency of the matrix.
Poly-1-vinylimidazole is a biocompatible nontoxic
> 3500 mg kg
) water-soluble polymer .
It was shown in  that metal-containing polymeric
composites and coatings based on a (co)polymer of poly-
1-vinyl-1,2,4-triazole and acrylamide can be formed by
the electrochemical method.
The electrosynthesis of silver(0)-containing nanocom-
posites and coatings on purely iron and steel electrodes
was performed by the electrochemical method, with the
electropolymerization of 1-imidazole combined with the
cathodic deposition of metals.
We demonstrated that nanocomposites and nanocom-
posite coatings containing 2–30 wt % silver are formed in
electrolysis of aqueous or aqueous-ethanolic solutions of
1-vinylimidazole (VIM) and acrylamide (AA) or mixtures
of these taken in various ratios in the presence of AgNO
(KI in some cases) only with an initiator of the peroxide
type (e.g., 4-tert-butylperoxy-4-oxobutanoic acid), whose
electroreduction potential is close to the deposition po-
tentials of metals, 0.6–1.2 V (s.h.e.).
On being dried, the nanocomposite coatings formed
on electrodes become insoluble in water and ordinary
Absorption bands peaked at 415 and 412 nm appear
in UV spectra of dark brown copolymeric nanocomposite
films at silver contents of 5.5 (sample I) and 8.5%
(sample II), respectively (Fig. 1). This indicates that
silver particles are formed in the nanosize zero-valence
state [1, 9]. The content of silver has been conﬁ rmed by
elemental analysis and atomic-absorption spectroscopy.
The type of distribution of silver nanoparticles in
the polymeric matrix and their size and concentration
depend on the potential at which the process is performed,
electrolysis duration, nature of a solvent and a polymeric
According to the data furnished by transmission
electron microscopy (TEM), silver nanoparticles in
samples I and II have sizes of 2–14 nm and are moderately

Abstract—Possibility of electrochemical formation of metal-polymeric nanocomposites and coatings on purely
iron and steel electrodes by combining the electrochemically initiated (co)polymerization of 1-vinylimidazole and
acrylamide with the cathodic deposition of metals was studied. Polymeric coatings were formed by the method
of contact exchange of metals. The structure and selected properties of metal-polymeric coatings were examined.
It was found that silver nanoparticles are uniformly distributed in the polymeric matrix. A thermogravimetric
analysis demonstrated that the metal-polymers synthesized possess a high thermal stability.
