Abstract

Mechanochemical synthesis, magnetic and electrical properties of organic polymer-based semiconductors containing para- and ferromagnetic particles have been considered. Semiconductors have been obtained from polyaniline (emeraldine base), polystyrene, FeCl3 · 6H2O, and elemental sulfur. The presence of iron nanoparticles is confirmed by means of scanning electron microscopy. The conductivity of polymer composites containing iron particles turns out to be several orders of magnitude higher than that of the initial undoped polyaniline. The temperature dependence of conductivity of composites exhibits the semiconducting pattern.
