N-Halamine-based antibacterial materials are widely used due to their excellent characteristics. However, the N-Cl bonds inN-halamine-based materials are not stable under UV light irradiation so that they are difficult to recover and reuse. Here, a kind ofN-halamine-immobilized Fe3O4@SiO2@TiO2(F@S@T-Cl) nanoparticles were prepared. In addition, the UV stability and regeneration capacity were also studied after variable time exposure to UV light. The results showed that nanoparticles have great antibacterial properties againstStaphylococcus aureusandEscherichia coli. Meanwhile, the N-Cl bond in the nanocomposite showed outstanding storage stability under UV light irradiation and good regeneration ability; the material can realize cyclic utilization and solve the problem of secondary pollution of the antibacterial material. It provides a broader application prospect for the recyclableN-halamine antibacterial material.
