Antibacterial Additive for Polystyrene Based on Silver Nanoparticles Supported on Titanium Dioxide

Silver nanoparticles supported on titanium dioxide nanoparticles (Ag/TiO2) were incorporated and evaluated as antibacterial additive for polystyrene materials. These particles were synthesized using a deposition-precipitation method by adding silver nitrate as metallic precursor, sodium hydroxide as...
