- Abstract
ABSTRACT The novel organic/inorganic conductive nanocomposites were synthesized via emulsion polymerization using sodium dodecyl sulfate as an anionic emulsifier and ammonium persulfate as an oxidant. The structure, morphology, and properties of the nanocomposite were characterized by Fourier transform infrared spectroscopy, Ultraviolet--visible spectroscopy, X-ray diffraction, thermogravimetric analysis (TGA), and field emission scanning electron microscopy. TGA results showed that the decomposition temperatures of nanocomposites were higher than the Poly(p-phenylenediamine). All synthesized nanocomposites showed a semicrystalline pattern. The conductivity of nanocomposites was measured by the four-probe method and it was found that the electrical conductivity of the nanocomposites increased by increasing the amount of Fe3O4 nanoparticles. The maximum electrical conductivity (3.15 × 10−3 S/cm) was obtained for a nanocomposite having 1:0.75 ratio of p-phenylenediamine-Fe3O4. The obtained nanocomposites were analyzed for their antioxidant activities using 2, 2-diphenyl-1-picrylhydrazyl assay and the results indicated a maximum antioxidant activity of 54% for the nanocomposite. © 2013 Wiley Periodicals, Inc.
