Soluble, Antibaterial, and Anticorrosion Studies of Sulfonated Polystyrene/Polyaniline/Silver Nanocomposites Prepared with the Sulfonated Polystyrene Template

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 reagents 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 solvents 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 waterborne alkyd resin.
