“…The Ag3d peaks of all of the Ag/PVA nanofibers were presented as two peaks, one at 366.7 eV and one at 372.7 eV. 44–46 The binding energy peaks of 366.7 and 372.7 eV were assigned as Ag3d 5/2 and Ag3d 3/2 , respectively. Typically, the area of the peak represents the amount of the component.…”

We investigated and compared three different methods for synthesizing Ag/PVA nanofibers by effectively dispersing and loading Ag particles onto PVA nanofibers and preventing the detachment of Ag from the nanofibers. The three methods were: (a) the solution reduction method (Method 1) in which the reduction of Ag+ was conducted before electrospinning, resulting in mixing the polymer and the Ag nanoparticles in the electrospinning solution; (b) the immersion method (Method 2) in which electrospun PVA nanofibers were immersed in the Ag+ solution, resulting in loading the Ag particles onto the PVA nanofibers; and (c) the nanofiber reduction method (Method 3) in which the Ag+/PVA solution underwent electrospinning followed by the reduction process with Ag+/PVA nanofibers. All of the electrospun nanofibers had a crosslinked structure that resulted from the chemical reaction of glutaraldehyde with the hydroxyl group of PVA, to prevent dissolution in the aqueous solution. Fourier transform infrared spectra provided evidence of the successful formation of the crosslinked structure of the nanofibers, and x-ray photoelectron spectroscopy and transmission electron microscopy confirmed the loading of Ag nanoparticles onto the nanofibers. The release profiles were investigated by inductively coupled plasma, and the morphology of the nanofibers was observed by scanning electron microscopy. Method 3 had the best performances for loading Ag particles onto the nanofibers and for minimizing the loss of Ag nanoparticles from the nanofibers. These findings identified an effective method for fabricating metal/polymer composite nanofibers, and will allow the expansion of the applications of metal/polymeric composite nanofibers.

“…The spinning process was made possible by the presence of water-soluble polyvinyl alcohol (PVA) among well-dispersed and nanosized additives. [28][29][30] Dangling hydroxyl groups were specically chosen to act as a molecular platform for further chemical crosslinking during the post-spinning heat-assisted mechanical development process.…”

“…47 Even with the chemical interaction, the in situ generated Ag particles preferentially form on the surface of the composites due to the migration of Ag + ions or Ag metal during the thermal reduction process in the polymer matrix with a lower glass transition temperature (T g ) than the processing temperature. 48 In this study, we fabricated Ag/soluble PI (SPI) composite lms. Since SPI can be solution processed in its imidized form, the in situ metallization method can be applied without any subsequent imidization process.…”
