ABSTRACT Public Textiles require high durability and safety, yet common materials like cotton, linen, silk, wool are prone to harboring pathogens experiencing mechanical deterioration due microbial activity. Developing fibers with exceptional antimicrobial properties for is crucial but challenging. Herein, a trace coordination bond crosslinking strategy was proposed prepare nano‐Cu 2 O/polylactic acid (Cu O/PLA) highly antibacterial activity, robustness, recyclability. The dynamic bonds allow uniform dispersion of O in PLA, improving molecular chain interfaces resulting excellent performance (tensile fracture strength 48.75 MPa). combination O's capacity PLA's weak acidity provides superior activity (99.99%) against various pathogens. This enables Cu O/PLA demonstrate an shelf life exceeding 6 months. Additionally, the ease breaking regenerating grants Therefore, this offers novel viable approach preparing nanocomposite PLA properties, addressing challenges faced Textiles.
