Mechanical and Antibacterial Properties of Polypropylene/Polyamide 6 Blends-TiO₂ Nanocomposites

摘要

Polypropylene/Polyamide 6 (PP/PA6) blends-TiO₂ nanocomposites have been prepared via melt blending PP/PA6 with TiO₂ nanoparticles, which were pretreated with toluene-2,4-di-isocyanate. The functionalized-TiO₂ can react with the terminal amino and carboxyl groups at PA6, interfacial interaction and compatibility between TiO₂ and matrix have been greatly improved resulted in higher tensile and impact strength than that of those filled with pristine TiO₂ or pure PP/PA6 blends, and they have strong antimicrobial abilities against Bacillus subtilis, Staphylococcus aureus and Escherichia coli. The average efficiency of antibacterial is over 90% within 2.0Â h. Mechanical and antibacterial properties can achieve their maximum with 3.0 wt%TiO₂.View full textDownload full textKeywordsAntibacterial properties, Mechanical properties, Polypropylene/polyamide 6 blends, Titanium dioxide nanoparticleRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/03602559.2012.671418
