Abstract: 

Polymer composite materials are prepared via the in situ synthesis of silver nanoparticles (AgNP) in a poly(urethane-urea) matrix. Interaction between polar functional groups of the matrix and a surface of AgNP in the nanocomposites leads to a rearrangement of the hydrogen bonding network between functional groups of the polymer matrix due to changes in its domain structure. It is shown that the urethane groups interact with AgNP via C=O, whereas the urea groups interact with the nanofiller via both C=O and NH moieties of polymer macrochains. Prepared polymer composites with low AgNP content are characterized by the enhanced thermal stability, reasonable hydrophilicity, and bactericidal activity.
