Abstract This article developed a novel antibacterial cotton fabric, whose photodynamic antibacterial component was a polymer photosensitizer (PNT) with aggregation induced emission properties obtained by copolymerization of tetrastyrene acrylamide and N-acryloyloxy succinimide. Its fluorescence performance and the generation of singlet oxygen were analyzed. In order to improve the antibacterial performance of cotton fabrics, 3-glycidoxypropyltriethoxysilane was used to treat the cotton fabrics, introducing epoxy groups and grafting polyhexamethylene guanidine hydrochloride. Finally, after PNT treatment, the cotton fabric was endowed with the antibacterial ability of photodynamic and guanidine cation synergistic effects. After 30 laboratory washes (equivalent to 150 home washes), the antibacterial cotton fabric still maintained an antibacterial rate of over 95% against S.aureus,E.coli and MRSA, demonstrating excellent durability. In addition, the study also evaluated the cytotoxicity of antibacterial cotton fabric, and the results showed that it had good biocompatibility. This antibacterial cotton fabric is expected to be applied in antibacterial underwear, medical bandages and other fields that require antibacterial properties.
