Abstract

The invention relates to the technical field of electrorheological fluid materials, in particular to high-conductivity electrorheological fluid and a preparing method thereof.Liquid metal and electrorheological fluid synthesized in situ serve as raw materials and are uniformly mixed to prepare the high-conductivity electrorheological fluid, good fluidity of the liquid metal is used for uniformly dispersing liquid metal particles into the electrorheological fluid synthesized in situ, and therefore conductivity of the electrorheological fluid is improved; as the liquid metal in the electrorheological fluid synthesized in situ is not effectively communicated, the prepared high-conductivity electrorheological fluid still keeps the insulation characteristic.The preparing method of the high-conductivity electrorheological fluid is simple, the materials are wide in source and easy to obtain, and applicability is high.

Description

Technical field [0001] The invention relates to the technical field of electrorheological fluid materials, in particular to a high-conductivity electrorheological fluid and a preparation method thereof. Background technique [0002] Electrorheological fluids (Electrorheological Fluids) are abbreviated as ER liquids or ER fluids, which are prepared by dispersing solid particles with high conductivity, low conductivity, and high dielectric constant in an insulating liquid with low dielectric constant. It is usually a suspension liquid. Liquid-solid transformation can occur under the action of electric field. When the applied electric field intensity is much lower than a certain critical value, the electrorheological fluid is liquid; when the electric field intensity is much higher than this critical value, it becomes solid; near the critical value of electric field intensity, it becomes viscous And it becomes larger with the increase of electric field intensity. Since electrorheo...
