Abstract
With the improvement of the hygiene awareness and pathogen prevention awareness of patients and medical staff, textiles with efficient and long-lasting pathogen inactivation effects are urgently needed. Photodynamic therapy (PDT) has rapidly developed into a new type of antibacterial technology due to its high antibacterial activity and has received widespread attention. However, the commonly used photosensitizers are mostly inorganic nanomaterials, which have poor adhesion to textiles and are not environmentally or human friendly. Here, we report a strategy of preparation of a sunlight-driven rechargeable antibacterial textiles based on natural antibacterial agents, which can work in light and dark conditions. The prepared BD-PTL@wool has long-lasting antibacterial properties, can rapidly produce ROS, and can store sterilization activity under light irradiation, ensuring all-day bacterial killing (>99.95 % under light irradiation and >99.80 % under dark conditions after light irradiation). BD-PTL@wool has excellent reusability, and the antibacterial rate can still above 95 % after repeated use for 5 times. In addition, BD-PTL@wool has excellent hydrophilic, UV resistance, biocompatibility and can withstand 50 washing cycles. The successful application of this strategy in textile preparation broadens the research idea for exploring the application of green photosensitive antibacterial materials in textile field.
