A combination of single screw extruder and hot press technique was used to fabricate these polymer nanocomposite films. These polymer nanocomposite films were prepared by mechanical mixing of 1% (w/w) of oil, anti-oxidant 0.05% (w/w), TPE-E granules 0.5% (w/w) and followed by single screw extruder to produce the pellets. As-prepared pellets were further melted for films in hot press technique. Antimicrobial activity was evaluated according to Japan Industrial Standard—JIS Z 2801 in TPE-E compounds against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). TPE-E samples containing additives 0.05 and 0.5% AgNPs_ZnO presented 75 and93%bactericidal reduction for Gram-negative bacteria Escherichia coli (E. coli) and 76 and 92% bactericidal activity reduction for Gram-positive bacteria Staphylococcus aureus (S. aureus), respectively.79-88closedAccesssilvernanoparticlesantimicrobial agentsthermoplasticspolyesterselastomerszinc oxidesCapítulo de livro10.1007/978-3-030-05749-7_9https://orcid.org/0000-0002-7626-880X
