Abstract
In this work, we report fabrication and antimicrobial activity of PSF/PVP based Cu and CuO membranes against human gram-negative bacteria Escherichia coli. These membranes were fabricated by electrospinning and have been fully characterized, including SEM, EDX and X-ray diff raction. SEM images of the composite membranes clearly showed presence and distribution of Cu and CuO nanoparticles on the PSF/PVP fi ber surfaces. The PSF/PVP based Cu and CuO nanoparticles membranes exhibited signifi cant antibacterial activity against E. coli, with no evidence of leaching, thereby positioning the composite membranes as potential antibacterial materials for water fi ltration, protective clothing and wound healing.
