Abstract

ABSTRACT A magnetorheological fluid (MRF) is a smart composite suspension composed of nonmagnetic liquid and soft magnetic particles. Carrier fluids can considerably influence the performance of MRFs; therefore, to investigate the effect of carrier fluids on MRFs, an SO/IL-MRF was prepared by mixing an ionic liquid (IL) with silicone oil (SO) in this study. Three types of MRF samples were prepared for experiments (pure SO, pure IL, and SO/IL). According to the experimental results, the SO/IL-MRF has better sedimentation stability than those based on pure SO and pure IL. Further, three methods were used to determine the shear yield stresses of the MRFs. The SO/IL-MRF achieved a higher shear yield stress than those of the other two because a network structure is formed between the ionic fragments and the molecular chains of the SO in the SO/IL-MRF. This increases the movement resistance of the particles in the carrier fluid, and it is unlike the mechanism of the IL-enhanced MRF. This work provides new ideas for improving the MRF performance. Graphical abstractSO/IL-MRF prepared by mixing ionic liquid with silicone oil exhibited better sedimentation stability and higher shear yield stress. This is because a network structure is formed between the ionic fragments and the molecular chains of the silicone oil, which increases the movement resistance of the particles in the carrier fluid

离子液体/硅油基磁流变液的性能及机理

磁流变液是一种由非磁性液体和软磁性颗粒组成的智能复合悬浮液。载液可显著影响磁流变液的性能；因此，为了研究载液对MRF的影响，本研究通过将离子液体（IL）与硅油（SO）混合制备了SO/IL-MRF。制备了三种类型的MRF样品用于实验（纯SO、纯IL和SO/IL）。根据实验结果，SO/IL-MRF比纯SO和纯IL具有更好的沉降稳定性。此外，还使用了三种方法来确定MRF的剪切屈服应力。SO/IL-MRF实现了比其他两种更高的剪切屈服应力，因为在SO/IL-MR中SO的离子片段和分子链之间形成了网络结构。这增加了载体流体中颗粒的运动阻力，并且与IL增强的MRF的机制不同。这项工作为提高MRF性能提供了新的思路。将离子液体与硅油混合制备的SO/IL-MRF具有较好的沉淀稳定性和较高的剪切屈服应力。这是因为在硅油的离子片段和分子链之间形成了网络结构，这增加了颗粒在载液中的运动阻力
