In situ generation of antibacterial copper nanocomposite fabrics by bioreduction with Moringa oliefiera leaf extract

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.
