Abstract

Aimed to obtain a material with improved rheological property, the Fe₃O₄-TiO₂ nanocomposites were prepared by a modified sol-gel processing. The structure and morphology of the Fe₃O₄-TiO₂ nanocomposites were examined by transmission electron microscopy (TEM), X-ray diffraction (XRD) analysis and Fourier transform infrared spectroscopy (FT-IR) analysis, etc. The magnetic property and the magnetorheological properties of the coated particles were also examined in detail. The experimental results demonstrated that such materials exhibited favorable magnetorheological (MR) effect, and the MR performance of them were dependent on the relative content of TiO₂ in the composite.
