| Summary: | <p>Ionic liquids are recently-developed smart materials that are not well known by mechanical engineers. They are of great interest due to their non-volatility, viscosity and extremely high electrical conductivity. Up to now, no reports have appeared on their rheological properties under magnetic or electrical fields.</p> <p>In this work, we study the electro-rheological behaviour of a newly presented ionic liquid (2-hydroxyethylammonium formate). Our experiments show that the ionic liquid is not sensitive to magnetic fields. Nevertheless, resonably high damping ratios (42.8%) have been attained under relatively low electric fields (0.6 kVcm<sup>-</sup><sup>1</sup>).</p> |
