Abstract In the paper an activity of functional groups of polyurethanes, like urethane, urea and biuret, on in-matrix stabilization of silver nanoparticles formed in situ was discussed in details. Polyurethane and poly(urethane-urea) matrices in the nanocomposites are characterized by relatively high level of interaction between their functional groups and silver nanoparticles (AgNP) where as poly(urethane-biuret) matrix are characterized by lower stabilizing activity related to AgNP because of strong hydrogen bonding interactions between biuret groups and other functions of polymer chains. All nanocomposite systems have intermediate level of water and moisture sorption, and high bactericidal activity. Prepared composites could be successfully applied as modern antimicrobial polymer materials.
