Resumo
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), Raman Spectroscopy, Differential
Scanning Calorimetry (DSC), biocidal tests against the bacteria Escherichia
coli and Staphylococcus aureus. The nanoparticles showed size between 150 and
200 nm and spherical form. HMSPP/SEBS/AgNPs/ZnO films incorporated with the
nanoparticles have demonstrated biocidal effect against the bacteria E. coli and S.
aureus when irradiated at 12.5 kGy.
