3,3′,4,4′-Benzophenone tetracarboxylic acid (BPTCA) could directly react with hydroxyl groups on cellulose to form ester bonds. The modified cotton fabrics not only provided good wrinkle-free and ultraviolet (UV) protective functions, but also exhibited important photochemical properties such as producing reactive oxygen species (ROS) including radicals (HO•) hydrogen peroxide (H2O2) under UV light exposure. amounts of the produced radical were measured, mechanism BPTCA treated was discussed. results reveal that possess washing durability in generation peroxide. different concentrations cured at an elevated temperature demonstrated excellent antimicrobial activities, which 99.99% antibacterial activities against both E. coli S. aureus. advanced materials have potential applications medical textiles biological material fields.
