Crosslinked polyurethanes (PUs) based on hyperbranched polyester and poly(dimethylsiloxane) (PDMS), which are thermosetting polymers, are one of the most representative products in the coating applications. To enhance the biomedical properties of PUs, we have attempted to incorporate PDMS as soft segments and silver-ferrite as nanoparticles in order to prepared PU nanocomposites (PU NCs). Silver ferrite nanoparticles were incorporated into crosslinked polyurethanes (PU NCs) with different soft poly(dimethylsiloxane) segments, via in situ polymerization. Herein, we report the nanomechanical properties, hydrophobicity and antifungal activities of PU NCs based on poly(dimethylsiloxane), 4,4’-methylenediphenyl diisocyanate and hyperbranched polyester of the second pseudogeneration, with different soft (PDMS) segment content. The nanomechanical properties of PU NCs were investigated by nanoindentation measurements, while the hydrophobicity of PU NCs was measured by water absorption properti...es. The fungicidal activities of PU NCs were evaluated against Candida albicans and Candida parapsilosis. PU NCs with lower soft segment content exhibited selective and good antifungal activity toward the tested fungi due to higher hydrophilicity and higher amount of Ag+ ion released. The selective fungicidal activity and low cytotoxicity of PU NCs with good nanomechanical properties ensure it is a candidate as coatings for medical devices.
