Abstract | dc.description.abstract | A set of poly(propylene) composites containing different amounts of copper nanoparticles
(CNP) were prepared by the melt mixed method and their antimicrobial behavior was
quantitatively studied. The time needed to reduce the bacteria to 50% dropped to half with
only 1 v/v % of CNP, compared to the polymer without CNP.
After 4 h, this composite killed more than 99.9% of the
bacteria. The biocide kinetics can be controlled by the
nanofiller content; composites with CNP concentrations
higher than 10 v/v % eliminated 99% of the bacteria in less
than 2 h. X-ray photoelectron spectroscopy did not detect
CNP at the surface, therefore the biocide behavior was
attributed to copper in the bulk of the composite. | en_US |
