Preparation and property of polyurethane/nanosilver complex fibers.

Highlights: [•] Utilizing terminal reactive groups in polyurethane, nanometer silvers were reduced in situ. And the PU/nanosilver complex fibers were produced by dry spinning. [•] The influence of nanosilver on the properties of PU was studied. [•] It is inferred that 0.030% Ag should be a proper concentration for the PU/nanosilver complex fibers with favorable mechanical properties and highly effective antibacterial activities.
