Abstract

Conjugated polymers such as polyaniline (PANI) and poly(3,4-ethylenedioxythiophene) (PEDOT) were coated on Fe₃O₄ magnetic nanoparticles via two different methods. Core-shell Fe₃O₄-PANI nanocomposite was synthesized through graft polymerization, whereas Fe₃O₄-PEDOT nanocomposites were synthesized by in situ chemical oxidative polymerization. Resulted nanocomposites were characterized for structural, morphological, electrical and magnetic properties by TEM, XRD, FT-K four-probe and SQUID, respectively. Both composites showed high electrical conductivity and magnetic saturation than that of the pure polymers.
