Abstract
Nanomaterials are finding the diversity of application at the leading edge in emerging field of nanotechnology. Coppernanoparticles (CuNPs) were in situ generated on the surface of cotton fabrics, using Achyranthes aspera leaf extract byenvironmentally benign green synthesis. The structural and morphological properties of synthesized nanocompositecotton fabrics (NCFs) were characterized by different spectral studies such as Fourier-transformation infrared (FTIR),scanning electron microscopy (SEM) coupled with energy-dispersive X-ray primary and derivative thermogravimetric(TG-DTG), differential scanning calorimetry (DSC), and X-ray diffractometer (XRD). The molecular functionalitiesof hydroxyl groups in polyphenols of A. aspera leaf extract were identified from FTIR absorption spectrum, and theyare responsible for the bioreduction of Cu+2 into Cu0 for the formation of CuNPs. The average size of the formedCuNPs from SEM studies was found to be 95 nm. The formed CuNPs were exhibited Face centered cubic (FCC)crystalline structure, and it was confirmed by XRD studies. TG-DTG analysis publicized the thermal stability ofNCFs. The tensile strength of NCFs was higher than normal cotton fabrics. These NCFs exhibited good antibacterialproperties which considered for making aprons and wound dressing materials in medicine and for packing materials
