Fig. 2a and b presents the photographs of the reaction system
corresponding to silver nanoprism solution with wool fibers before
and after coloration. The blue color of silver nanoprism faded gradually
in the solution during the process of coloration and finally the
solution was colorless after the reaction finished, which implied
that most, if not all, silver nanoprisms were assembled onto the
wool fibers. The extinction spectra of silver colloidal solution before
and after coloration are shown in Fig. 2c. The solution after
wool coloration had scarcely any extinction peak (curve b). This
demonstrated further that the assembling of silver NPs onto the
wool fibers was quite complete, with virtually no silver NPs left
in the final solution. The modified wool fabrics inherited the optical
properties of silver NPs. As shown in Fig. 3, the wool fabrics
appeared in vivid colors derived from the LSPR of silver NPs. However,
the colors of these treated wool fabrics were slightly different
from that of silver NP solutions, which is due to the environment
changes around silver NPs from water to the interface of air and
wool fiber [13,14].
