賈雪瑩　王騊

摘要：為制備具有光催化和抗菌性能的功能織物，采用低溫水熱法，使用TiCl3為Ti源，在滌綸織物表面垂直生長TiO2納米棒，制備了包覆有TiO2納米棒的柔性有機織物。利用SEM、TEM、FTIR、XRD和XPS等對復合織物的結(jié)構(gòu)和形貌進行表征和分析，并測試復合織物在紫外光下的光催化性能和可見光下的抗菌性能。結(jié)果表明：該復合織物在紫外光照射下可有效降解有機污染物，與商業(yè)化P25納米顆粒涂覆織物相比較具有更好的光催化性能。可見光照射2 h后，對大腸桿菌和金黃色葡萄球菌具有大于99%的抗菌性。制備的功能織物在光催化降解有機污染物和抗菌方面具有廣泛的應用前景。

Preparation of TiO2 nanorod composite fabric and its photocatalytic

and antibacterial properties

JIA Xueying， WANG Tao

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 lowtemperature 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 nanoparticlecoated 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.

隨著紡織業(yè)的不斷發(fā)展，人們對織物的耐用性，多功能性和智能性的需求不斷增長。具有抗菌、防靜電、自清潔、防紫外線、阻燃及不同環(huán)境的溫度調(diào)節(jié)等性能的功能性織物已成為織物領域不可或缺的一部分[14]。基于紡織品良好的柔性、透氣性和易加工性能，研究人員嘗試將納米材料與紡織品相結(jié)合制備功能性織物，通常構(gòu)建功能性織物需要將具有微調(diào)或功能性納米材料添加到織物上，即通過納米技術(shù)增強織物的功能性。

二氧化鈦（TiO2）作為一種綠色無污染的光催化劑被廣泛應用于環(huán)境修復、儲能、光催化水分解和抗菌應用等領域[58]。為了獲得具有自清潔，抗菌，抗靜電和抗紫外線等多功能性織物，研究人員嘗試將TiO2納米材料與織物相結(jié)合。……
