摘要
以葡萄籽提取物为生物还原剂,采用一步法工艺在真丝织物上原位合成和沉积纳米银粒子。通过反应溶液的颜色变化及紫外-可见吸收光谱曲线确定了纳米银的生成。葡萄籽提取物纳米银粒子的表面等离子共振峰（SPR）出现在426 nm处,并通过测定其透射电子显微镜（TEM）和扫描电子显微镜（SEM）得知纳米银粒子基本呈现球形或者近似球形,平均粒径为40 nm。通过测定EDS能谱图确定了真丝织物表面有银元素存在。在生物还原剂浓度相同的条件下,随着硝酸银浓度的增加,更多的纳米银粒子发生了原位生成并沉积在真丝织物表面。处理后的真丝织物具有优异的水洗、摩擦、耐光色牢度及抗菌性能,经30次水洗后,抑菌率仍可达98%以上。
The simple one-step process for the in-situ synthesis and deposition of silver nanoparticles （AgNPs） on silk fabric by using grape seed extract as bioreductant is presented. The formation of AgNPs is confirmed by the color change of the solution and UV-Vis spectra. The surface plasmon resonance （SPR） peak of grape seed extract AgNPs is observed at 426 urn, and the morphology of AgNPs is visualized as spherical or roughly spherical by TEM and SEM images. The surface of AgNPs treated silk fabric features roughness due to the deposition of AgNPs and the uniform distribution of roughly spherical AgNPs on silk surface is observed by SEM images. The existence of silver element is also confirmed by EDS analysis. On the condition of same concentration of bioreductant solution, an increase in the amount of silver nitrate may result in more silver being deposited on the surface of silk fabric. The treated silk fabrics show excellent antibacterial activity and color fastness to washing, rubbing and light, and its inhibition rate remains 98-/o or more after 30 times of home launderings.
