Antimicrobial Property of Polypropylene Composites and Functionalized Copper Nanoparticles.

Copper nanoparticles (CuNPs) functionalized with polyethyleneimine (PEI) and 4-aminobutyric acid (GABA) were used to obtain composites with isotactic polypropylene (iPP). The iPP/CuNPs composites were prepared at copper concentrations of 0.25-5.0 wt % by melt mixing, no evidence of oxidation of the ... View More
