Abstract

Abstract

The Fe₃O₄-polyaniline(Fe₃O₄-PANI)nano-composites are synthesized via an in-situ polymerization of aniline monomer in SDBS-HCl aqueous solutions which contain well-dispersed Fe₃O₄nanoparticles, SDBS serving as surfactant and dispersant. The composites are characterized by means of XRD, TEM, FT-IR, et al. The results show that competing doping behavior happened between SDBS and HCl during the process of synthesis. The component of the composite is Fe₃O₄-PANI-DBSA. Fe₃O₄particlesin it are almost spherical with average size of 13 nm and dispersed in the base of PANI regularly. These composites possess good electrical conductivity and magnetization. With the content of Fe₃O₄increased from 7.79% to 35.34%, the conductivity of these composites gradually decreases from 1.71 S/m to 0.41 S/m, meanwhile the saturated magnetization(σ_s)increases from 6.14 A· m²/kg to 18.11 A·m²/kg, and the coercive force(Hc)is within the range of 0.52 A/m-0.73 A/m.
