Loading of ZIF‐67 on silk with sustained release of iodine as biocompatible antibacterial fibers

Antibacterial fibers have great potential in numerous applications, including bandages, surgical robes, and surgical sutures, and play a significant role in our everyday lives. Here, zeolitic imidazolate framework‐67 was synthesized using a green method on silk fibers through a layer‐by‐layer process under ultrasonic irradiation (ZIF‐67@silk [U]) and without ultrasonic irradiation (ZIF‐67@silk [B]). Then, iodine was loaded on ZIF‐67@silk samples and were assessed as antibacterial fibers with iodine release. Four samples of ZIF‐67@silk and I 2 @ZIF‐67@silk were characterized by FT‐IR, PXRD, FE‐SEM, TGA, BET, and UV–Vis spectroscopy. Finally, antibacterial activity of ZIF‐67@silk (B and U) and I 2 @ZIF‐67@silk (B and U) on Staphylococcus aureus as Gram‐positive bacteria and Escherichia coli as Gram‐negative bacteria was investigated. In addition to ZIF‐67@silk samples, iodine‐loaded samples showed excellent antimicrobial facility.
