Description
Summary:Nanocomposites with antimicrobial activity are of great interest nowadays and the development of titanium dioxide with these functional properties presents interest in academic and industrial sectors. An approach to develop PE nanocomposite containing Ag nanoparticles to have an antimicrobial effect is presented. To obtain such antimicrobial nanocomposites, LDPE/EVA were processed with Ag nanoparticles on Ti02 particles as inorganic carrier substance. Titanium dioxide nanoparticles （P-25） were covered with silver nanoparticles using Turkevich Method or citrate reduction method. The Ag/TiO2 nanoparticles were dispersed at concentration of 0.5 wt%, 0.8 wt% and 1 wt% in LDPE/ethylene vinyl acetate copolymer （EVA）-（50% w/w） at the melt state in a Haake torque Rheometer. Silver nanoparticles were characterized with UV-Vis Spectroscopy. The nanocomposites thus prepared were characterized through Ares Rheometer, Scanning Electronic Microscopy （SEM） and JIS Z 2801 antimicrobial tests to study the effects of the addit
