Abstract

This study examines the interfacial rheological properties of magnetorheological fluids in oil-based systems, with a particular focus on liquid–liquid interfaces, including particle-laden emulsions and multilayer films. In this work, interfacial shear rheology of MRF without magnetic fields has been investigated, with exclusive emphasis on interfacial viscoelastic behaviour. Experimental (using bi-conical IRS) techniques are employed to assess the interfacial behaviour, and we thoroughly studied and quantified how MRF particles form films and behave at the oil interface under different shear conditions. Our analysis establishes a direct link between interfacial rheological behaviour and interfacial structural organisation, particularly particle coverage and network formation. Steady shear experiments visualise the evolution of interfacial particle assemblies, revealing irreversible rearrangements that govern viscoelastic behaviour.

用界面流变学分析磁流变流体，矿物油界面的相行为和力学性能之间的相互关系

本研究考察了油基体系中磁流变流体的界面流变特性，特别关注了液-液界面，包括颗粒负载乳液和多层膜。在这项工作中，研究了无磁场磁流变材料的界面剪切流变学，重点研究了界面粘弹性行为。实验（使用双锥IRS）技术评估了界面行为，我们深入研究和量化了不同剪切条件下磁流变液颗粒在油界面上的成膜和行为。我们的分析建立了界面流变行为和界面结构组织之间的直接联系，特别是颗粒覆盖和网络形成。稳定剪切实验可视化界面颗粒组装的演变，揭示了控制粘弹性行为的不可逆重排。图形抽象
