Facile synthesis and immobilization of Ag–TiO2 nanoparticles on electrospun PU nanofibers by polyol technique and simple immersion

A simple polyol process is presented here to synthesize silver (Ag) nanoparticles (NPs) on titanium nanosphere substrate (Ag–TiO2), which are subsequently decorated on the surface of electrospun polyurethane (PU) nanofibers by immersion in hot colloidal solution. Various spectroscopic and physical characterization techniques are utilized to study the physico-chemical properties of the prepared samples. The polyol-synthesized Ag–TiO2 decorated PU nanofibers show superior antibacterial properties under UV light, and are potentially useful for water filtration application.
