摘要
以2-硝基苯甲醛为稳定剂制备了金纳米粒子,进而合成了金纳米粒子改性靛蓝染料,通过X射线衍射仪(XRD)、X射线光电子能谱仪(XPS)、紫外分光光度计(UV-vis)等确认了其结构。对染色棉织物进行了上染率、力学性能和抗菌性能等测试。研究结果表明:金纳米粒子改性靛蓝对棉织物的染色性能优于商业靛蓝,经其染色的棉织物具有良好的抗菌性能,对金黄色葡萄球菌与大肠杆菌的抑菌率分别为95%和90%。
2-nitrobenzaldehyde was used as stabilizer to generate gold nanoparticles(AuNPs),and then AuNPs modified indigo was synthesized.X-ray diffractometer(XRD),X-ray photoelectron spectroscopy(XPS),ultraviolet spectrophotometer(UV-vis)were applied to confirm the structure.The dye uptake,mechanical properties and antibacterial properties of dyed cotton fabrics were tested.The results showed that AuNPs modified indigo had excellent dyeing property and antibacterial property.The antibacterial ratios against Staphylococcus aureus and Escherichia coli were 95% and 90%,respectively.
