Resumo
The purpose of present study is to evaluate the antimicrobial potential of
Thermoplastic Polyester Elastomer (TPE-E) incorporated with zinc oxide added with
colloidal dispersion of metallic silver adsorbed on pyrogenic silica (AgNPs_ZnO).
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.
