通过将二氧化硅和银纳米粒子复合在羊毛纤维表面，实现了羊毛织物新的多功能性能。由于银纳米颗粒的局部表面等离子体共振，改性的羊毛织物支持明亮的颜色。首先将二氧化硅纳米粒子组装在羊毛纤维上，然后将银纳米粒子吸附在羊毛纤维上。利用傅里叶变换红外光谱仪和扫描电镜对整理后的羊毛织物进行了表征。结果表明，二氧化硅纳米粒子和银纳米粒子在羊毛纤维上结合在一起。改性后的羊毛纤维表面纳米二氧化硅的存在增强了羊毛织物的色泽，并使羊毛纤维具有超亲水性。此外，由于银纳米粒子的存在，二氧化硅和银纳米粒子的羊毛织物表现出明显的抗菌活性。
New multifunctional properties of wool fabrics were achieved through combining silica and silver nanoparticles on the surface of fibres. The modified wool fabrics support bright colours due to the localised surface plasmon resonance of silver nanoparticles. Silica nanoparticles were first assembled on the wool fibres, and then silver nanoparticles were adsorbed on the fibre. Fourier transform infrared spectroscopy and scanning electron microscopy were used to characterise the surface features of the treated wool fabrics. The results indicated that the silica nanoparticles and the silver nanoparticles were combined together on wool fibres. The existence of silica nanoparticles on the fibres enhanced the colour of the modified wool fabrics and produced super-hydrophilic property in wool fibres. Moreover, the wool fabrics with silica and silver nanoparticles showed obvious antibacterial activity because of the presence of the silver nanoparticles.
