Water-assisted self-assembly of polyaniline/Fe₃O₄ composite honeycomb structures film

4-dodecylbenzenesulfonic acid-doped polyaniline/Fe₃O₄ composite honeycomb structure film is obtained by water-assisted self-assembly method. The morphologies of this honeycomb structure film were studied by transmission electron microscopic and atomic force microscropy, while the Fourier transform infrared spectra were obtained to illustrate its composition. This as-prepared film with conducting polymers and magnetic inorganic compounds is proved to show superparamagnetic property. Fabrication of 3D ordered macro-porous structures with conducting polymers and magnetic inorganic compounds should lead to applications in electronic-magnetic materials.
