Disponível em: http://repositorio.ipen.br/handle/123456789/31852.http://repositorio.ipen.br/handle/123456789/31852In 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.429-435closedAccesszinc oxidesantimicrobial agentsnanoparticlesantibioticsCapítulo de livro10.1007/978-3-030-36628-5_410000-0002-6481-0155https://orcid.org/0000-0002-7626-880X
