Facile and environmental benign in situ synthesis of silver nanoparticles for multifunctionalization of wool fibers

Abstract

In this manuscript, we report the simple method to multifunctional wool fiber surfaces. The multifunctional wool fibers were devised with brilliant coloration, antimicrobial activity, and UV-protection property. These multifunctional properties were progressed by in situ assemble of silver nanoparticles (Ag NPs) into the wool fiber surface using green cleaner one-pot route. The proteins existing in the wool fibers acted being a redox active bio-template, facilitating the reduction of Ag⁺ to Ag⁰, with simultaneous binding of the produced Ag NPs both on the surface and within the center of the wool fibers. The entire results showed that the Ag NP in situ-incorporated wool fibers can be used as colorant wool fibers effectively, and these colored fibers also exhibit an improvement for multi-functionality properties.
