The processes of copper reduction on the steel surface in the presence of a polymer protector were researched to determine the effect of the polymer pseudo-matrix on the characteristics of the resulting nanoparticles. Poly(N-vinylpyrrolidone) with different molecular mass, poly(ethylene glycol) and poly(ethylene glycol monolaurate) were used as a polymer pseudo-matrix. Transmission electron microscopy, scanning electron microscopy, electron spectroscopy, and thermogravimetric analysis were used to characterize the synthesis products. It was found that in the presence of a polymer protector, nanocomposite particles are formed, including copper-containing particles and a polymer. It is shown that the nature of the polymer affects the morphological structure of nanocomposites formed on the surface of steel. In the presence of poly(N-vinylpyrrolidone), spherical agglomerates consisting of smaller copper particles are formed. In the presence of poly(ethylene glycol monolaurate), needle-like structures are formed. In the presence of poly(ethylene glycol), dendritic structures are formed. In this case, copper nanoparticles of 3-10 nm size are formed directly on the steel surface in the presence of poly(N-vinylpyrrolidone) or poly(ethylene glycol monolaurate).
