Novel Fe3O4/reduced graphene oxide (RGO) composite nanoparticles were synthesized and confirmed by FT-IR spectra as good candidates for magnetic stimuli-responsive magnetorheological (MR) materials. The morphology of Fe3O4/RGO was observed by both scanning and transmission electron microscopy and their sedimentation stability improved due to a decreased density of the synthesized composites. The MR performance of the Fe3O4/RGO-based fluid was investigated with a rotational rheometer, and the Cho-Choi-Jhon model of the rheological equation of state was adopted to explain their performances for the entire shear rate region.
新型 Fe3O4/还原氧化石墨烯（RGO）复合纳米粒子通过傅里叶变换红外光谱（FT-IR）进行了合成和确证，是磁刺激响应磁流变（MR）材料的理想候选材料。通过扫描电子显微镜和透射电子显微镜观察了 Fe3O4/RGO 的形态，由于合成复合材料的密度降低，其沉降稳定性得到提高。通过旋转流变仪研究了基于 Fe3O4/RGO 的流体的磁流变性能，并采用 Cho-Choi-Jhon 流变状态方程模型解释了它们在整个剪切速率区域的性能。
