Abstract

Stable aqueous dispersions of silver (Ag) nanoparticles were prepared by reducing silver nitrate solutions with sodium borohydride (NaBH4) in the presence of waterborne polyurethane as a stabilizing agent. WPU/Ag nanocomposites were obtained after evaporating water. Transmission electron microscope (TEM) shows nanoscale Ag particles are well dispersed in WPU matrix at a lower concentration, while particles exhibit a little aggregation at a higher concentration. UV-visible spectra, X-ray powder diffraction, and energy dispersive X-ray spectrometer (EDS) confirm the existence of Ag particle in WPU matrix. TheWPU/Ag composite films show good antibiotic ability.
