Abstract

Polymer nanocomposite films of polypropylene and AgNPs were prepared by melt extrusion using twin-screw extruder. These polymer nanocomposites were further modified by y-irradiation in acetylene at dose of 12.5 kGy The AgNPs (silver nanoparticles) used in this study were synthetized using sonochemical method from silver nitrate precursor. The polymer nanocomposites were evaluated using differential scanning calorimetry (DSC), X-Ray diffraction (XRD), FTIR spectroscopy and Scanning electron microscopy (SEM). We have also studied the antibacterial activity of these polymer nanocomposite films against two different groups of bacteria-Staphylococcus aureus (S. aureus; gram-positive bacteria) and Escherichia coli (E. coli; gram-negative bacteria).
