Nano-sized iron oxides face-centered cubic (Fe3O4) and rhombohedral (α-Fe2O3) have been successfully prepared by thermal decomposition of ferric ion doped poly aniline-co-o-anthranilic acid (PANAA). Ferric ion doped PANAA was synthesized by oxidative chemical polymerization of aniline and o-anthranilic acid monomers. Iron oxides have been characterized by XRD and SEM. Nanoparticles size of mixed iron oxides was in the range of 3–6 nm. The XRD analysis revealed a broad pattern of FCC and cubic crystal structure of iron oxide. FTIR, UVVisible spectra measurements and TGA as well as the conductivity of pure copolymer and copolymers/iron(III) composites have been studied.
