Study on Performances of Various Magnetic Fluid/polyaniline Nanoparticles

摘要

The performances of various magnetic fluid (water- based Fe<,3>O<,4> magnetic fluid, Fe<,3>O<,4> magnetic colloidal particle, silicon-oil-based Fe<,3> O<,4> magnetic fluid, and NiZnFe magnetic fluid)/polyaniline nanoparticles. were investigated using infrared spectrometry (IR), transmission electron microscope (TEM), scanning electron microscope (SME) and X-ray diffraction (XRD), and their electromagnetic properties were also measured. The results showed that four kinds of magnetic fluid/polyaniline nanoparticles possessed the core- shell structure, and the conductivities of the various magnetic fluid/polyaniline nanoparticles are lower than that of polyaniline. For the various magnetic fluid/polyaniline nanoparticles, the conductivitiy for NiZnFe magnetic fluid/polyaniline nanoparticle is largest, and reaches 7.23s/cm, while the conductivitiy for water-based Fe<,3>O<,4> magnetic fluid/polyaniline nanoparticle is least, and only reaches 0.85s/cm.
