Abstract

Two kinds of oil-based stabilized dispersion of Fe ₃O ₄ nanoparticles were prepared by thermal decomposition and surface modification of water-based Fe ₃O ₄ nanoparticles synthesized by coprecipitation method. Process conditions for preparing Fe ₃O ₄ nanoparticles by thermal decomposition were optimized. The effects of thermal decomposition temperature and aging time on particles size, morphology and magnetic properties were studied. Oil-based stabilized dispersion, particles size and morphology, specific saturation magnetization and surface properties were characterized by TEM, VSM and FTIR. Compared with Fe ₃O ₄ nanoparticles prepared by surface modification, it is found that the stability of Fe ₃O ₄ nanoparticles prepared by thermal decomposition is better, but its magnetic response property is worse.
