Abstract: Silver nanocomposites in the matrix of a copolymer of 1-vinyl-1,2,4-triazole with methacrylic acid were synthesized by the electrochem. method by combining the process of electrochem. polymerization with cathodic precipitation of metals on metal electrodes. Structure and composition of the obtained nanocomposites and nanocoatings were recorded using UV, IR, at. absorption, and X-ray spectroscopy, thermogravimetric and elemental analyses. Transmission electron microscopy data show that the synthesized nanocomposites consist of particles with a diameter of 1 to 12 nm, predominantly spherical.
