Microstructure and Properties of Ferrite/Organic Nanocomposite Prepared with Microemulsion Method

Abstract:

A magnetite composite composed of the organic compounds and Fe₃O₄ nanoparticles was prepared with microemulsion method. The Tween 80 and ammonia were used as surfactant and reducing agent, respectively, in synthesizing the Fe₃O₄ nanoparticles. The experimental results showed that the composite possessed good stability while the volume ratio of Tween 80 to butanol was 0.4 and the molar ratio of NH₄OH to Fe³⁺ was 14.6. The saturation magnetization of the composite depends on the molar ratio of NH₄OH to Fe³⁺. The mechanism of this stable Fe₃O₄ paste was realized by the Fe₃O₄ nanocomposite film using TEM. The microstructures of the film show that the magnetic nanoparticles in the composite are surrounded by Tween 80, which separates the magnetic nanoparticles and leads to good stability.
