Preparation and Conductive and Electromagnetic Properties of Fe₃O₄/PANI Nanocomposite via Reverse In Situ Polymerization

In this paper, the magnetite/polyaniline (PANI) nanocomposite was prepared by the novel reverse in situ polymerization method. Fe 3 O 4 magnetic nanoparticles were synthesized in situ in PANI chloroform solution to form a suspension containing the Fe 3 O 4 /PANI nanocomposite. It overcame the disadvantage of oxidation of the Fe 3 O 4 by the oxidant in conventional method. The Fe 3 O 4 /PANI chloroform suspension and the Fe 3 O 4 /PANI powder...
