Abstract Using tamarind leaf extract as a reducing agent and various concentrated aq⋅AgNO3 solutions as source, the silver nanoparticles (AgNPs) were in situ generated in polyester fabrics. The nanocomposite polyester fabrics were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction and antibacterial tests. The size of the generated AgNPs varied between 50 and 120 nm. The X-ray analysis indicated the generation of both AgNPs and AgO nanoparticles in the nanocomposite fabrics. The nanocomposite polyester fabrics exhibited excellent antibacterial activity against both the Gram negative and Gram positive bacteria and hence can be considered for making antibacterial textiles.

使用罗望子叶提取物还原剂原位生成银纳米粒子的纳米复合聚酯织物

摘要 以罗望子叶提取物为还原剂，以各种浓缩 aq·AgNO3 溶液为来源，在涤纶织物中原位生成银纳米粒子 (AgNPs)。通过扫描电子显微镜、傅里叶变换红外光谱、X射线衍射和抗菌试验对纳米复合涤纶织物进行了表征。生成的 AgNPs 的大小在 50 到 120 nm 之间变化。X 射线分析表明在纳米复合织物中同时产生了 AgNPs 和 AgO 纳米颗粒。纳米复合聚酯织物对革兰氏阴性菌和革兰氏阳性菌均表现出优异的抗菌活性，因此可考虑用于制造抗菌纺织品。
