“…The colloidal nickel solution was also subjected to ultrasonic treatment for 10 min on an ultrasoundifier VSX 500 2008. The colloidal solution of nickel was transferred to a Petri dish and dried in an air for 24 h [16]. The reaction and the scheme for the formation of nickel nanoparticles can be shown by the following reaction:…”

The polymer nanocomposite structures based on isotactic polypropylene and nickel nanoparticles were obtained and studied by scanning electron microscopy, UV-Vis, FT-IR, and dielectric spectroscopy. IR studies show that the introduction of nickel nanoparticles into the polypropylene matrix does not change the chemical structure of the polymer, that is, nickel nanoparticles are not in the chemical, but in physical interaction with the polymer. It is also shown that as the frequency increases, the value of the permittivity of the nanocomposite based on PP/Ni does not change, and this is due to the lack of polarization processes. The value of the dielectric loss tangent depends on the Ni concentration with an extremum, that is, with an increase in the content of Ni nanoparticles, the value of the dielectric loss tangent decreases and at a content of 3% Ni in the polymer, the value of tan δ is minimal and a further increase in the concentration leads to an increase in the dielectric loss tangent. A sharp decrease in the resistivity at 383 K, 413 K, and 423 K, respectively, for the nanocomposites PP/3% Ni, PP/5% Ni, and PP/10% Ni is explained by the destruction of the crystalline phase of the polymer and the increase in electrical conductivity of the nanocomposites.
