Nanomaterials are finding diversity of application at the leading edge in emerging field of nanotechnology. Copper nanoparticles (CuNPs) were in situ generated on the surface of cotton fabrics, using Achyranthes aspera (A. aspera) leaf extract by environmentally benign green synthesis. The structural and morphological properties of synthesized nanocomposite cotton fabrics (NCFs) were characterized by different spectral studies such as Fourier transformation infrared (FTIR), Scanning electron microscopy (SEM) coupled with Energy dispersive X-ray (EDX) Primary and derivative thermogravimetric (TG-DTG), Differential scanning calorimetry (DSC) and X-ray diffracto meter (XRD). The molecular functionalities of hydroxyl groups in polyphenols of A. aspera leaf extract were identified from FTIR absorption spectrum and they are responsible for bio reduction of Cu+2 into Cu0 for the formation of CuNPs. The average size of the formed CuNPs form SEM studies was found to be 95nm. The formed CuNPs were exhibited FCC crystalline structure and it was confirmed by XRD studies. TG-DTG analysis publicized thermal stability of NCFs. The tensile strength of NCFs was higher than normal cotton fabrics. These NCFs exhibited good antibacterial properties which considered for making aprons, wound dressing materials in medicine and for packing materials.

Key words: Nanocomposite cotton fabrics; in situ generation; Achyranthes aspera leaf extract; Mechanical properties; Antibacterial activity.
