Abstract

A versatile process employing anionic surfactants has been developed for the preparation of processible nanocomposite films with electrical conductivity and magnetic susceptibility. Maghemite (g-Fe₂O₃) nanoclusters (∼10 nm in size) are coated with 4-dodecyl-benzenesulfonic acid, and polyaniline (PAn) chains are doped with 10-camphorsulfonic acid. The coated nanoclusters and doped polymers are soluble in common solvents, and casting the solutions readily gives free-standing nanocomposite films with nanocluster contents as high as ∼50 wt %. The g-Fe₂O₃/PAn nanocomposites show high conductivity (82-237 S cm^-1) and magnetizability (up to ∼35 emu/g g-Fe₂O₃).
