英文摘要Polymer materials with strong bactericidal properties by impregnating or complexing antibacterial agents were used in daily life. However, based on polymer matrices, the simultaneous acquisition of more environmentally and friendly self-cleaning and sterilization properties may be more beneficial to human health. Herein, a petal-like network photocatalytic beta-Bi2O3/Bi2O2.7 heterostructure film with a thickness of ca 0.81 mu m was gradually formed layer upon layer on polyvinyl chloride (PVC) polymer matrices through one-step hydrothermal process for the first time, and decorated Ag nanoparticles as co-catalyst. The Ag-decorated beta-Bi2O3/Bi2O2.7 heterostructure film showed hydrophobicity, degradation of 97% Rhodamine B (RhB) in 150 min, inactivation of > 99.99% Escherichia coli (E.coli) in 18 h, and E.coli anti-adhesion performance. The photocatalytic properties were mainly ascribed to the generation of center dot O-2(-) and h(+) due to the synergistic effects of petal-like hierarchical microstructure, good interface quality and accelerated carriers separation among beta-Bi2O3, Bi2O2.7 and Ag particles. Furthermore, it was found that the grown of the bismuth oxide film on polymer matrices in the hydrothermal environment was selective to the types of polymer matrices. Our design can provide a reference to construct other photoactive functional films on polymer matrices and further collaborative applications and have the potential application prospects in the building and medical field.
