The article presents the results of the synthesis and study of the structure of metal-polymer complexes based on polyethylene (propylene) glycol maleinates with acrylic acid and metals p-EGM:AA/Ag, p-EGM:AA/Ni, p-EGM:AA/Ag-Ni, p-PGM:AA/Ag, p-PGM:AA/Ni, p-PGM:AA/Ag-Ni using microscopy, spectroscopy and thermogravimetry methods. The resulting nanocomposites contain isolated Ag0 nanoparticles with a diameter of 60 ± 10 nm, predominantly spherical in shape and metallic Ni0, 70 ± 10 nm in size, cubic in shape, uniformly distributed in the polymer matrix, agglomerates on the surface of the polymer matrix in the range of 150–200 nm. The synthesized nanocomposites have thermal stability up to ~900 ºС. The authors have studied the antimicrobial activity of the p-PGM/AA-Ag metal-polymer complex, which showed high efficiency against standard strains of Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus.
