(A) Schematic of an indirect method for the fabrication of metallic nanofibers. (B) SEM image of composite nanofibers comprising of PVA and copper acetate. (C and D) SEM image of Cu nanofibers at (C) low and (D) high magnifications produced after calcination of the composite nanofibers in air at 500 °C, showing fusion at the cross-points. (E) TEM image of the Cu nanofibers. (F) Schematic of an indirect, template-assisted method for the fabrication of metallic nanofibers by depositing metals on the surface of as-spun polymer nanofibers, followed by selective removal of the polymer template. (G and H) Top-view SEM images of a network of intertwined Au nanofibers at (G) low and (H) high magnifications, showing fusion at the cross-points. (I) SEM image of the cross-section of a single Au nanofiber, revealing its hollow shape. (A−E) Reprinted with permission from ref 287. Copyright 2010 American Chemical Society.
