PREPARATION AND ANTIBACTERIAL PROPERTIES OF ORGANIC- INORGANIC POLYMER HYBRIDS USING NANO-TIO2

Organic-inorganic polymer hybrids of were prepared by melt compounding using a twinscrew extruder. Polyamide6 (PA6) was selected due to its fiber performance, while nanosized titania (TiO2) was used as inorganic filler due to its function. Silver nano-particles were successfully doped to the PA6/TiO2 hybrids by immersing them in aqueous silver nitrate solution followed by UV irradiation through photo-depositing mechanism. All the hybrids doped with silver showed excellent antibacterial properties against Escherichia coli, Klebsiella pneumonia and Staphylococcus aureu .
