Abstract
Nanocomposite cotton fabrics with in situ generated copper nanoparticles (CuNPs) were prepared using Pterocarpus santalinus (Red sanders) aqueous extraction as a reducing agent. The nanocomposite cotton fabrics made using different concentrated aqueous CuSO4.5H2O source solutions were characterized by scanning electron microscopy (SEM), Fourier transformation infrared (FTIR) spectroscopy, and antibacterial tests. The SEM analysis of nanocomposites indicated the presence of spherical CuNPs in the size range of 71–190 nm. FTIR spectra indicated the involvement of hydroxyl and ether groups of aqueous extraction of Red sanders powder in the in situ generation of CuNPs. These nanocomposite fabrics showed good antibacterial activity against Escherichia coli bacteria. These nanocomposite cotton fabrics with in situ generated CuNPs can be considered in the medical field for wound cleaning and wound dressing purpose and for making aprons.
