Abstract

Silk is widely used in the production of high-quality textiles. At the same time, the amount of silk textiles no longer in use and discarded is increasing, resulting in significant waste and pollution. This issue is of great concern in many countries where silk is used. Hydrogen peroxide as a naturally occurring compound is an important indicator of detection in both biology and the environment. This study aims to develop a composite fiber with hydrogen peroxide-sensing properties using discarded silk materials. To achieve this goal, firstly, polydopamine (PDA) was used to encapsulate the ZnFeO NPs to achieve the improvement of dispersion, and then regenerated silk fibroin (RSF) and PDA@ZnFeO/RSF hybrid fibers are prepared by wet spinning. Research has shown that PDA@ZnFeO/RSF demonstrates exceptional sensitivity, selectivity, and stability in detecting hydrogen peroxide, while maintaining high mechanical strength. Furthermore, the complete hybridization of PDA@ZnFeO with silk fibroin not only results in the combination of the durability of silk fibroin and PDA@ZnFeO’s rigidity, ensuring a reliable service life, but also makes PDA@ZnFeO/RSF exhibit excellent catalytic activity and biocompatibility. Therefore, the composite fiber exhibits exceptional mechanical properties and reliable hydrogen peroxide sensing capabilities, making it a promising material for biological and medical applications.
