Synthesis of Silver Nanoclusters and Nanoparticles in the Medium of Hyperbranched Polyester Polyamine, and the Morphology and Aggregation Properties of the Metal–Polymer Nanocomposite
RUSSIAN JOURNAL OF INORGANIC CHEMISTRY(2023)
摘要
procedure was developed for the single-step synthesis of a metal–polymer nanocomposite based on silver nanoparticles and second-pseudogeneration superbranched polyester functionalized along the periphery with 3-[(2-aminoethyl)amino]propionate. Under the conditions of the synthesis in the medium of H 2 O or DMSO, hyperbranched polyester decorated with ethylenediamine moieties can act as both a reductant of the nanoscale silver state and a stabilizer of it. The synthesized composite nanomaterial is formed by aggregates of hyperbranched polyester polyamine doped with Ag(0) nanoclusters and nanoparticles of spheroidal symmetry with a face-centered cubic crystal lattice. The hydrodynamic diameter of aggregates and the diameter of particles increase with increasing molar ratio n_Ag^ + / . -0emNHCH_2CH_2NH_2 and are 34–90 and 7–14 nm, respectively.
