Polystyrene, PS, particles of 450nm diameter and poly(styrene-co-styrene sulfonate), PSS, particles of140-160 nm diameter were prepared by emulsifier-free emulsion polymerization. The surfaces of the PS and PSSparticles were coated with Ag nanoparticles for the application of antimicrobial agents by reduction of Ag ions usingγ-irradiation. The Ag-PS and Ag-PSS were characterized by High-Resolution Transmittance Electron Microscopy(HR-TEM), Field-Emission Scanning Electron Microscopy (FE-SEM), and Energy Dispersive X-ray Spectroscopy(EDXS). The HR-TEM and EDXS data showed that the Ag nanoparticles were loaded on the surface of the PS andPSS particles, respectively. The antimicrobial efficiency of the Ag-PS and Ag-PSS particles (0.4 g) with ca.100 ppmAg, which was coated onto yarn (KS K 0905-1996 rule), was tested against Staphylococcus aureus ATCC 6538 andKlebsiella pneumoniae ATCC 4352 after 100 washing cycles (KS K 0432-1999 rule). The antimicrobial efficiencyof the Ag-PS particles against Staphylococcus aureus ATCC 6538 and Klebsiella pneumoniae ATCC 4352 was99.9% after 100 cycles washing., confirming that the Ag-PS particles can be used as antimicrobial agents.
