Preparation and Characterization of Antibacterial Electrospun Polyurethane Fibers Containing TiO2-Ag Nanoparticles
A novel antibacterial material was prepared by electrospining polyurethane (PU) containing TiO2-Ag nanoparticles in this study. The average diameter of PU electrospun nanofibers decreased with increasing concentration of TiO2-Ag.These nanofibers membrane showed high antibacterial activities against Staphylococcus aureus and Escherichia coli, respectively. The mixed mode of PU electrospun fibers and TiO2-Ag nanoparticles was a physical form. The addition of TiO2-Ag did not affect the mechanical property of the mat much.
