Magnetic Fe 3 O 4 –poly(aniline‐ co ‐ o ‐anthranilic acid) nanoparticles were prepared by a novel and simple method: anthranilic acid assisted polymerization. The synthetic strategy involved two steps. First, Fe 3 O 4 nanoparticles capped by anthranilic acid were obtained by a chemical precipitation method, and then the aniline and oxidant were added to the modified Fe 3 O 4 nanoparticles to prepare well‐dispersed Fe 3 O 4 –poly(aniline‐ co ‐ o ‐anthranilic acid) nanoparticles. Fe 3 O 4 –poly(aniline‐ co ‐ o ‐anthranilic acid) nanoparticles exhibited a superparamagnetic behavior (i.e., no hysteresis loop) and high‐saturated magnetization ( M s = 21.5 emu/g). The structure of the composite was characterized by Fourier‐transform infrared spectra, X‐ray powder diffraction patterns, and transmission electron microscopy, which proved that the Fe 3 O 4 –poly(aniline‐ co ‐ o ‐anthranilic acid) nanoparticles were about 20 nm. Moreover, the thermal properties of the composite were evaluated by thermogravimetric analysis, and it showed excellent thermal stability. © 2006 Wiley Periodicals, Inc.
