(a) Reflectance spectra of the nanofibers decorated with silver nanoparticles after 1- and 3-min immersion in the Tollen’s reactive. In the inset, from left to right: Macroscopic images of the polyacrylonitrile (PAN) fibers, bare, functionalized with amidoxime, and functionalized with silver nanoparticles. (b) Representative SEM image of the fibers after the electroless plating step. (c) Representative transmission electron microscopy (TEM) image of the fibers after the electroless plating step. In the inset, size distribution of the nanoparticles. Reproduced with permission from Zhang et al. [341]. Copyright (2012), American Chemical Society.
