摘要：以植物金银花提取物作为还原剂制备了纳米 ZnO 和纳米 Ag，通过浸轧法将纳米 ZnO 单独整理以及
将两者依次整理到棉织物上制备多功能棉织物（ZnO-棉织物、ZnO/Ag-棉织物）。利用 SEM、XRD、FTIR
分析了整理前后棉织物的形貌和结构，并探讨了整理后棉织物的多功能性。结果表明，棉织物上的纳米粒
子分布较均匀且发生了轻微团聚。与 ZnO-棉织物相比，ZnO/Ag-棉织物对亚甲基蓝（MB）和红酒的降解率
分别提高了 7.09%和 10.61%，说明纳米 Ag 提升了纳米 ZnO 的光催化活性。ZnO-棉织物经过 10 次洗涤后
其纳米粒子含量虽有小幅下降，但对 MB 的降解率仍达到 83.24%以上，说明负载纳米粒子后棉织物具有良
好的自清洁能力和耐洗性能。此外，ZnO-棉织物和 ZnO/Ag-棉织物的紫外防护系数（UPF）值分别达到 33.23
和 41.06，对大肠杆菌和金黄色葡萄球菌的抑菌率均达到 95%以上，表现出优良的抗紫外线性和抗菌性能。

Abstract: Honeysuckle extracts were used as reducing agent to prepare nano zinc oxide and nano silver,
and then the cotton fabric was treated with nano zinc oxide alone, or further with nano silver step by step to
prepare multi-functional cotton-based fabrics (ZnO-cotton fabric, ZnO/Ag-cotton fabric). The morphology
and structure of cotton fabrics before and after finishing were analyzed by SEM, XRD and FTIR, and the
versatility of cotton fabrics after finishing was discussed. The results showed that the distribution of
nanoparticles on the cotton fabrics were relatively uniform and slightly agglomerated. Compared with those
of ZnO-cotton fabric, the decomposition rates of ZnO/Ag-cotton fabric to Methylene Blue (MB) and Red
Wine increased by 7.09% and 10.61%, respectively, indicating that nano silver improved the photocatalytic
activity of nano zinc oxide. Although the adsorption amount of nano particles in ZnO-cotton fabric
decreased slightly after 10 times of washing, both decomposition rates to MB still reached more than
83.24%, indicating that the cotton fabrics had good self-cleaning ability and washing resistance
performance after loading nanoparticles. In addition, the cotton fabrics exhibited excellent UV resistance
and antibacterial properties. The UV protection factor (UPF) values of ZnO-cotton fabric and
ZnO/Ag-cotton fabric reached 33.23 and 41.06, and the antibacterial rates against E. coli and S. aureus
reached more than 95%.
