摘要

目前的研究重点是银纳米颗粒(AgNPs)的合成、表征及其在棉织物上的应用，以提高棉织物的抗菌性能和力学性能。本文采用溶胶-凝胶法还原盐合成纳米颗粒，并采用机械固热技术将其应用于棉织物表面。各种仪器测试，如紫外光谱，锌化分析和扫描电子显微镜(SEM)进行表征合成的纳米颗粒。AgNPs的尺寸约为60 nm，形状近似球形。利用细菌还原系统检测织物对金黄色葡萄球菌(革兰氏阳性)和大肠杆菌(革兰氏阴性)的抑菌活性。结果表明，对革兰氏阳性菌和革兰氏阴性菌均有良好的抑菌性能。纳米处理织物的机械性能也得到了明显的改善。目前的研究重点是银纳米颗粒(AgNPs)的合成、表征及其在棉织物上的应用，以提高棉织物的抗菌性能和力学性能。本文采用溶胶-凝胶法还原盐合成纳米颗粒，并采用机械固热技术将其应用于棉织物表面。各种仪器测试，如紫外光谱，锌化分析和扫描电子显微镜(SEM)进行表征合成的纳米颗粒。AgNPs的尺寸约为60 nm，形状近似球形。利用细菌还原系统检测织物对金黄色葡萄球菌(革兰氏阳性)和大肠杆菌(革兰氏阴性)的抑菌活性。结果表明，对革兰氏阳性菌和革兰氏阴性菌均有良好的抑菌性能。纳米处理织物的机械性能也得到了明显的改善。

Development of antimicrobial activity and mechanical performances of cotton fabric treated with silver nano particles (AgNPs)

The current research focuses on the synthesis, characterization and application of silver nano particles (AgNPs) on cotton fabric to create the antimicrobial property and improve its mechanical performances. Here nano particles are synthesized by reduction of salt in sol-gel method and applied on cotton fabric surface by mechanical thermo fixation technique. Various instrumental tests like UV spectroscopy, zetasize analyzing and scanning electron microscopy (SEM) are carried out to characterize the synthesized nano particles. The size of AgNPs is found about 60 nm and the shape is approximately spherical. The antimicrobial activity of treated fabric is examined against two bacteria named S. aureus (gram positive) and E. coli (gram negative) by bacterial reduction system. The result shows very good antimicrobial property in both gram positive and gram negative bacteria. An appreciable improvement on mechanical performances of nano treated fabric is also obtained.The current research focuses on the synthesis, characterization and application of silver nano particles (AgNPs) on cotton fabric to create the antimicrobial property and improve its mechanical performances.
