Abstract

The mechanochemical synthesis and magnetic and electric properties of organic polymeric semiconductor that contains paramagnetic and ferromagnetic particles are reported. Polyaniline, polystyrene, Fe[Cl.sub.3] and elemental sulfur are used as starting materials in order to obtain semiconductor polymer composite containing magnetic iron nanoparticles and having flexible thermomechanical properties.

Abstract

Nanocomposites of polyaniline with some rare earth chlorides like neodymium chloride, europium chloride, and dysprosium chloride are prepared by chemical oxidative polymerization of aniline and their morphological, structural, thermal, optical, magnetic and electrical properties are studied. Permittivity of the sample is dominated by the grain boundary behavior in low frequency and by the grain phase in the high frequency and a Maxwell-Wagner capacitor model is used for describing the frequency dependence of real part of impedance.

Abstract

Hybrid vertical architecture transistors are prepared, which has shown magnetic-field dependent electrical characteristics by using tris-(8-hydroxyquinoline) aluminum ([Alq.sub.3]), sulfonated polyaniline (SPAN), and n-type silicon. The rate of electrons that cross emitter and base layers and reach the collector is shown to be affected by the magnetic field, which has led to magnetic-field-dependent common-emitter current gain larger than 1.

Abstract

A new giant magnetoresistance (GMR) material composed of polyailine, polystyrene, sulfur, manganese acetylacetonate, lanthanum, and praseodymium chlorides is described. The external magnetic field has increased conductivity of films and the analysis of transient current kinetics after application of constant voltage to samples have shown the existence of three types of charge carriers ([e.sup.-], [H.sup.+] and [Cl.sup.-].

Abstract

Novel electromagnetic functional and cage-like polyaniline (PANI) composite micro/nanostructures containing ferromagnetic and octahedral Co[Fe.sub.2][O.sub.4] crystal are prepared by using Fe[Cl.sub.3] as both oxidant and dopant via a self-assembly process. The cage-like composite nanostructures have high conductivity and have also shown a typical ferromagnetic behavior.
