Herein, an efficient and rapid one‐step approach to construct CS@Ag nanohybrids through in‐situ reduction of AgNO3 with L‐ascorbic acid using chitosan (CS) as carrier only at room temperature was presented. Novel polyurethane/CS@Ag composite films with remarkable properties were fabricated via the reaction of CS@Ag nanohybrid as an antibacterial and reinforcing agent with bis(2‐hydroxyethyl) terephthalate (BHET)‐based polyurethane. With the increase of CS@Ag content, the antibacterial rate for polyurethane against Staphylococcus aureus and Escherichia coli increases. The antibacterial rate of polyurethane with 20 phr CS@Ag against S. aureus is 85.5%, and that containing 30 phr CS@Ag against E. coli is 94.9%. Thereby, the synergistic effect of CS and Ag can effectively improve the antibacterial rate of polyurethane. Meanwhile, the bond strength and tensile strength of polyurethane containing 20 phr CS@Ag are up to 8.72 MPa (improved by 74.3%) and 20.1 MPa (enhanced by 130.5%), respectively. Indeed, this work may unlock new possibilities for developing antibacterial and enhanced polyurethanes, which are expected to applied in the medical devices, food packaging, and automotive industries.Highlights CS@Ag was efficiently fabricated by in‐situ reduction via a one‐step approach. BHET is used as a novel chain extender for PU. CS@Ag is able to fully exert the synergistic effect of CS and Ag. CS@Ag endows PU with high strength and excellent antimicrobial properties.

Herein, this study reports the development of a multifunctional conductive antibacterial cotton fabric through the utilization of the natural polyphenol-mediated silver mirror reaction. The experimental results demonstrate that polyphenols can effectively facilitate the deposition of silver nanoparticles (AgNPs), resulting in a uniform and durable hybrid nanocoating on the cotton fabric. The effects of polyphenol’s molecular weights on the coating structures and stabilities have been revealed via two distinct approaches: washing resistance and electrochemical testing systems. It has been concluded that lower-molecular-weight phenols induce a compact and dense coating structure, whereas polyphenols such as tannic acid exhibit relatively high stability, achieving an excellent conductivity of 0.2 S/cm and a good washing resistance of 67% over five cycles. The underlying mechanism has been further confirmed by the cyclic voltammetry measurements, suggesting that polyphenols play a significant role in stabilizing AgNPs and preventing their dissolution. Furthermore, the Ag-doped polyphenol-coated fabrics exhibit notable antibacterial properties. By coupling natural polyphenols with typical silver mirror reactions, this study not only offers a sustainable alternative to synthetic chemicals but also presents a promising method to endow cotton textiles with the dual properties of conductivity and antibacterial activity.
