In this study, the nanoparticles of Zinc oxide (ZnO) and Zinc oxide doped with Silver (ZnO/Ag), were synthesized in laboratory. The incorporation of these nanoparticles in the blend of High Melt Strength Polypropylene (HMSPP) and Styrene-Ethylene/Butadiene-Styrene (SEBS) was carried by melt processing. The obtained materials were evaluated by X-ray diffraction (XRD), UV-visible spectra, Raman Spectroscopy, Differential Scanning Calorimetry (DSC), biocidal tests against the bacteria E.coli and S.aureus following the JIZ 2801 norm. The particles showed size between 150~200 nm and spherical form. The irradiated film, by gamma source at 12.5 kGy, for exposision of AgNP on ZnO-doped-Ag, of HMSPP/SEBS films incorporated with the nanoparticles has showed biocidal effect against the bacteria E.coli and S.aureus.
