Abstract—Copper-polymer coatings were for the ﬁ rst time deposited by combining the cathodic electrodeposition
of an amine-containing polyelectrolyte and the electrolytic deposition of copper. It was found that the coatings
have heat-conducting properties and their composition and structure were studied.
The methods used to deposit paint-and-lacquer coating
in the industry include that for obtaining single-layer and
priming coatings on a metallic surface by electrodeposi-
tion of water-reducible paint-and-varnish materials based
on polymeric electrolytes as ﬁ lm-forming agents. An
advantage of this technique is that it can form uniform-
thickness coatings in 1–2 min under nearly waste-free
production conditions. The method consists in that a
polyelectrolyte loses its solubility when the pH value in
the near-electrode space is changed due to the electrolysis
of water under the action of a current .
The technology of cathodic electrodeposition of
polymeric electrolytes is similar to galvanic processes
in which metallic coatings are deposited. Both processes
are performed in an aqueous solution, and the coating is
formed on a negatively charged substrate, the cathode.
This circumstance gave an impetus to development of
a new venue of R&D activities aimed to create metal-
polymer coatings by combining these processes.
Metal-polymer coatings have advantages of a poly-
meric coating, such as high elasticity and low density,
and, at the same time, acquire certain properties charac-
teristic of metallic coatings, namely, hardness, electrical
conductivity, heat conductivity, etc. At the same time,
the attractive feature is the opportunity for creating in
the near-layer conditions in which nanosize particles of
the meal are formed in its electrochemical reduction in
the presence of a polymer.
Of particular interest is to create coatings containing
copper particles because copper is known to possess high
heat-conducting properties, which is responsible for its
use in various heat-removal devices.
It has been shown for the examples of nickel-polymer
 and zinc-polymer  coatings that metal-polymer
coatings can be, in principle, produced by the cathodic
The goal of our study was to consider the possibility
of obtaining copper-polymer coatings by the cathodic
electrodeposition method and to study their properties.
As the polymeric electrolyte served the ﬁ lm-forming
agent of the industrial paint-and-varnish material for
cathodic electrodeposition (analogs: Cathogard W
781309 from BASF and GEN 6W 780/973 from PPG
company), which has the form of an epoxyamine adduct
modiﬁ ed with blocked polyisocyanate and converted to
the water-soluble state via interaction with acetic acid.
As the inorganic component was used copper acetate.
It was accepted in [3, 4] that the optimal conditions
for obtaining a good-quality coating are those in which
