摘　　要：In this work, multifunctional sulfonated polystyrene/polyaniline/silver （SPS/PANI/Ag） nanocomposites are prepared through using sulfonated polystyrene （SPS） spheres as templates and utilizing polyvinylpyrrolidone （PVP） as reducing agent and stabilizing agent. Our method is an environmentally friendly method because no toxic rea- gents are added during the preparation process. Fourier transform infrared spectrum （FTIR）, field emission scanning electron microscopy （FESEM）, and energy disperse spectroscopy （EDX） results confirmed the formation of PS spheres, SPS spheres, SPS/PANI nanocomposites, and SPS/PANI/Ag nanocomposites. Powder X-ray diffraction （XRD） patterns indicate that the obtained Ag nanoparticles are crystalline. Solubilities measurements show that SPS/PANI/Ag nanocomposites have improved solubilities when compared to pure PANI in common organic sol- vents and deionized water. Antibacterial studies show that SPS/PANI/Ag nanocomposites can greatly inhibit the growth of Escherichia coli and Staphylococcus aureus. Anticorrosion studies show that the incorporation of SPS/PANI/Ag nanocomposites in waterborne alkyd resin can greatly promote＇the anticorrosive efficiency of water- borne alkyd resin.In this work, multifunctional sulfonated polystyrene/polyaniline/silver （SPS/PANI/Ag） nanocomposites are prepared through using sulfonated polystyrene （SPS） spheres as templates and utilizing polyvinylpyrrolidone （PVP） as reducing agent and stabilizing agent.
