In this study, a new method utilizing electron beam irradiation to immobilize zinc-imidazolate MOF (ZIF-8) onto cotton fabric was reported, resulting in antimicrobial textiles with excellent durability.
Textiles modified with antimicrobial nanomaterials have excellent comprehensive performance. However, the shedding of nanoparticles often occurs in actual use. This not only reduces the service life of antimicrobial textiles, but also causes potential harm. Here, we report a new method to covalently immobilize a zinc-imidazolate MOF (ZIF-8) onto cotton fabric by electron beam irradiation to prepare antimicrobial textiles with excellent durability. A series of characterization analysis showed the electron beam irradiation did not damage the structure of the ZIF-8 nanoparticles and the particles were successfully introduced onto cotton fibers via poly hydroxyethyl acrylate (PHEA). The modified cotton fabric exhibited >99% inhibition of Escherichia coli, Staphylococcus aureus and Candida albicans. The results of dry cleaning and rub resistance tests showed that the prepared antimicrobial cotton fabric had significant durability which was attributed to the strong covalent binding between the MOF and textile.
