Owing to a variety of applicability of metal nanoparticles (MNPs), they have been introduced to diverse substrates. In particular, much effort has been devoted to the deposition of MNPs to polymeric 2D substrates, e.g., fabric or membrane, due to their strong antimicrobial activity. However, traditional methods for introducing MNPs (direct impregnation or in-situ reduction) have been limited because of the low deposition and the release of MNPs by the weakness of nanoparticle-substrate interactions. Here, we present the robust, antimicrobial active metal-fabric and -membrane nanocomposites with high deposition efficiency and durability of MNPs using the strong metal-sulfur covalent bond. This robust covalent bond leads to the marked suppression of the release of MNPs from the substrate and the sustainable antimicrobial activity in excess of 99.9%. This makes them tremendously attractive in applications ranging from eco-friendly environmental materials to advanced biomedical materials. |
