Abstract
The poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonate)–Fe 3O 4 (PEDOT/PSS–Fe 3O 4) nanoparticles have been prepared by using polystyrene sulfonic sodium (NaPSS) as a dispersant and dopant. The characterization of nanocomposites was investigated by transmission electron microscope, X-ray diffraction, UV spectroscopy, electrochemical study, four-probe, thermogravimetric analysis and magnetic property measurement system. XRD revealed the presence of spinel phase of Fe 3O 4 and the average size was calculated to be about 12 nm. The conductivity of nanocomposites at room temperature is excellent and it depends on the Fe 3O 4 content. The thermal stability of composites is outstanding. Higher saturation magnetization of 6.47 emu g −1 (20 wt.% Fe 3O 4) was observed at 300 K.
