Abstract

Copper nanoparticles (CuNPs) on nanocomposite fabrics (NCFs) were in situ produced by environmentally benign green route method, utilizing leaf extraction of Moringa oliefiera (MO) as reductant. The biosynthesized CuNPs in NCFs were analyzed by spectroscopic techniques like X-ray Diffractometer (XRD), Fourier Transform Infrared (FTIR), Scanning electron microscope (SEM) associated with Energy dispersive X-ray (EDX), Differential scanning calorimetry (DSC), and Thermogravimetric analysis (TGA). The NCFs were tested for their antibacterial property against Gram negative (G^-ve) and Gram positive (G^+ve) pathogens and also studied their mechanical properties, using universal testing machine. The shape of generated CuNPs was found to be spherical and exhibited with a mean size of 95 nm. The thermograms from TGA showed that the NCFs were thermally stable up to 404 °C. The XRD results are in apart with SEM analysis and showed the crystalline nature of CuNPs. The NCFs also exhibited good tensile strength at higher loads.

利用辣木叶提取物作为还原剂，通过环境友好的绿色途径原位生产纳米复合织物（NCFs）上的铜纳米颗粒（CuNPs）。通过诸如X射线衍射仪（XRD），傅立叶变换红外（FTIR），与能量色散X射线（EDX）相关的扫描电子显微镜（SEM），差示扫描量热法（DSC），和热重分析（TGA）。测试了NCF对革兰氏阴性（G ^-ve）和革兰氏阳性（G ^{+ ve}）的抗菌性能）病原体，并使用通用测试机研究了它们的机械性能。发现产生的CuNP的形状是球形的，并且呈现出95nm的平均尺寸。来自TGA的热分析图显示，NCF在高达404℃的温度下是热稳定的。XRD结果与SEM分析分开显示了CuNPs的晶体性质。NCF在较高载荷下也表现出良好的拉伸强度。
