摘要

A multifunctional cotton fabric was fabricated by in-situ synthesis of zeolitic imidazolate framework-8 (ZIF-8) on a polydopamine (PDA)-modified cotton substrate. Leveraging the reducing capability of PDA, silver nanoparticles (Ag NPs) were simultaneously incorporated into and around the ZIF-8 nanocrystals. The successful fabrication of the Ag/ZIF-8 functional cotton fabric was confirmed by characterization techniques including SEM, XRD, XPS, and TG. The modified fabric exhibits exceptional photocatalytic performance and cycling stability, achieving 93.4% degradation of methylene blue (MB) under visible light irradiation within 170 min and retaining 90.2% efficiency after three degradation cycles. Furthermore, the synergistic effect between Ag and ZIF-8 endows the fabric with significant antibacterial activity and efficient heavy metal ion adsorption capacity. Therefore, this study provides a novel strategy for designing multifunctional materials, holding significant promise for advancing the development of multifunctional textiles.
