Аннотация: We report on mechanochemical synthesis and magnetic and electric properties of organic polymericsemiconductor that contains paramagnetic and ferromagnetic particles. As starting materials we usedpolyaniline emeraldine base, polystyrene, FeCl3, and elemental sulfur. These components werechosen for the purpose of obtaining semiconductor polymer composite containing magnetic ironnanoparticles and having flexible thermomechanical properties. The presence of nanoparticles wasevidenced by scanning electron microscopy. The value of conductivity of the Fe-doped polymercomposite was increased by several orders of magnitude compared to the initial undopedpolyaniline. Temperature dependence of the conductivity shows semiconductor character of thecomposite material.
