Description 760-765
Nanocomposite cotton fabrics (NCCFs) with in situ formed copper nanoparticles (CuNPs) using aqueous extraction of
citrus lemon leaves as reducing agent have been made. The NCCFs have been analyzed by SEM, FTIR, XRD and TGA
techniques and antibacterial test. The CuNPS have been roughly spherical in shape with a mean size in the range of 82-114
nm. The OH and C-OH groups of leaf extract has played an important role in the generation of the CuNPs in the NCCFs as
established by the FTIR spectral analysis. The XRD analysis has indicated that the formation of CuNPs in NCCFs lowered
the crystallinity of NCCFs. The thermal stability of NCCFs has been lowered by the CuNPs. However, the NCCFs with in
situ generated CuNPs exhibited higher antibacterial activity against both gram-negative and gram-positive bacteria and
hence can be effectively used as antibacterial wound dressing and hospital bed materials.
