Abstract
Selenium (Se0) nanoparticles are stabilized with water-soluble polymers containing ionogenic groups of the different signs, namely, poly(N,N,N-trimethylammonium)ethyl methacrylate iodide (polycation) and sodium polystyrenesulfonate (polyanion). A comprehensive comparative study of the resulting selenium-containing nanodispersions by the UV–visible spectroscopy, atomic force and transmission electron microscopy, and dynamic and electrophoretic light-scattering methods is conducted. The effect of the charge sign of the polymer stabilizer on the structural–morphological, dimensional, electrochemical, and spectral characteristics of selenium-containing nanodispersions is shown.
