In the graph, the effect in the antibacterial activity of time and filler content in isotactic polypropylene (iPP)/ZnO composites is reported. Neat iPP has no bactericidal activity. For the composites, a decrease in the E. coli concentration is observed by increasing time. The effect is more evident for iPP/ZnO 95/5.
