摘要/Abstract

摘要： 为制备具有光催化和抗菌性能的功能织物,采用低温水热法,使用TiCl₃为Ti源,在涤纶织物表面垂直生长TiO₂纳米棒,制备了包覆有TiO₂纳米棒的柔性有机织物。利用SEM、TEM、FTIR、XRD和XPS等对复合织物的结构和形貌进行表征和分析,并测试复合织物在紫外光下的光催化性能和可见光下的抗菌性能。结果表明:该复合织物在紫外光照射下可有效降解有机污染物,与商业化P25纳米颗粒涂覆织物相比较具有更好的光催化性能。可见光照射2 h后,对大肠杆菌和金黄色葡萄球菌具有大于99%的抗菌性。制备的功能织物在光催化降解有机污染物和抗菌方面具有广泛的应用前景。

Abstract: To prepare a functional fabric with photocatalytic and antibacterial properties, a flexible organic fabric coated by TiO₂ nanorod was prepared using TiCl₃ as Ti source through low-temperature hydrothermal method by growing TiO₂ nanorod vertically on the surface of polyester fabric. The structure and morphology of the composite fabric were characterized and analyzed using SEM, TEM, FTIR, XRD and XPS. Then, the photocatalytic properties of the composite fabric under ultraviolet light and the antibacterial properties under visible light were tested. The results show that the composite fabric is able to effectively degrade organic pollutants under ultraviolet light irradiation. Compared with commercial P25 nanoparticle-coated fabric, it has better photocatalytic properties. After visible light irradiation for 2 h, its antibacterial activity against Escherichia coli and Staphylococcus aureus exceeded 99%, indicating that the functional fabric prepared in this study has broad application prospects in photocatalytic degradation of organic pollutants and antibacterial performance.
