摘要：

Flower-like Fe2O3/polyaniline core/shell nanocomposite was obtained via a two-steps method. Firstly, monodispersed flower-like iron oxide was synthesized by a high temperature refluxing method. Then flower-like Fe2O3/polyaniline core/shell nanocomposite was further obtained via the in-situ polymerization. Scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), SQUID MPMS, UV-vis and Haake rheometer were used to investigate its structure, morphology and properties. The obtained Fe2O3/polyaniline nanocomposite reveals an interesting morphological combination of hierarchical and core/shell structure. Its electrorheological (ER) behavior were investigated using a rotational rheometer under different applied electric field strengths when dispersed in silicone oil, which shown an obvious ER activity.
