文摘

Novel Ag-doped TiO₂ perpendicular nanosheet films were synthesized by a mild solvothermal method. The width of TiO₂ nanosheets was facilely tuned by controlling reaction time, and furthermore the pattern of TiO₂ nanosheets was easily obtained via predesigned seed layer. The antibacterial effects of Ag−TiO₂ thin films against Escherichia coli and Staphylococcus aureus were examined by film attachment method. The coating films showed excellent performance in killing bacteria under UV light. Moreover, the potent antimicrobial ability of the film was well-sustained even in the dark environment.
