Structure of electrorheological fluids
Physical Review Letters, 1990Electrorheological (ER) fluids are colloidal suspensions of highly polarizable particles in a nonpolarizable solvent. In a strong electric field, the behavior of the fluid is dominated by the dipolar interactions between the colloidal particles. We address problems of structure formation and long-time relaxation in an ER fluid.

Russian Journal of General Chemistry, 2010
Advances in one of the most promising fields of the chemistry of smart materials, specifically, electrorheological fluids are considered. The electrorheological effect and the structure and properties of electrorheological fluids are described. Modern views on the nature of the electrorheological effect are considered.

Electrorheology of Graphene Oxide
ACS Applied Materials & Interfaces, 2012Novel polarizable graphene oxide (GO) particles with oxidized groups on their edge and basal planes were prepared by a modified Hummers method, and their electro-responsive electrorheological (ER) characteristics when dispersed in silicone oil were examined with and without an electric field applied. The fibrillation phenomenon of this GO-based electro-

Polymer, 2021
Abstract Polyindole particles were prepared by the oxidative polymerization, where ammonium peroxydisulfate was used as an oxidant at several mole ratios to indole. Prepared spherical micrometre-sized polyindole particles were further used as a dispersed phase in silicone-oil electrorheological (ER) fluids and their rheological behaviour was ...

Electrorheological Toners for Electrophotography
Journal of Colloid and Interface Science, 2002The electrorheological (ER) behavior of pigment suspensions dispersed in a nonaqueous solvent was examined for their application as liquid toners for electrophotography. In electric fields, particles can align into chains along the field vector by dielectric polarization forces and the suspensions undergo a rapid transition from Newtonian fluids to ...

Rheology of electrorheological fluids
Physical Review Letters, 1992We present experimental and theoretical results on the shear thinning of electrorheological fluids. Rheological measurements on a model fluid consisting of monodisperse silica spheres immersed in a dielectric liquid show a power-law dependence \ensuremath{\mu}\ensuremath{\propto}\ensuremath{\gamma}${\mathrm{\ifmmode \dot{}\else \.{}\fi{}}}^{\mathrm ...

First Observation of Electrorheological Plasmas
Physical Review Letters, 2008We report the experimental discovery of "electrorheological (ER) complex plasmas," where the control of the interparticle interaction by an externally applied electric field is due to distortion of the Debye spheres that surround microparticles (dust) in a plasma.

MOLECULE-BASED ELECTRORHEOLOGICAL MATERIAL, ELECTRORHEOLOGICAL PERFORMANCE AND MOLECULE STRUCTURE
International Journal of Modern Physics B, 2011Molecule-based electrorheological (ER) materials as a novel type of ER materials, a series of compounds using melamine ( C 3 N 6 H 6) as the substrate, have been synthesized using orthophosphoric acid ( H 3 PO 4), oxalic acid ( H 2 C 2 O 4), 4-toluenesulfonic acid (PTA, C 7 H 8 O 3 S ) and 5-sulfosalicylic acid (SSA, C 7 H 6 O 6 S ), respectively as ...

Electrorheological tactel elements
Mechatronics, 2005Abstract The use of ultrasound systems for medical examination and diagnosis is nothing new. The extension of ultrasound techniques for real time elastographic analysis purposes represents a more recent development. Nevertheless, as they stand all such techniques rely on the interpretation of two-dimensional visual data displayed on a video screen ...

Electrorheological Fluid Hysteresis
Materials, 2005Electrorheological (ER) fluids are suspensions of polarizable particles dispersed in insulating liquids. They exhibit a rapid and reversible transition from a liquid-like to a solid-like state upon the application of an electric field. The observed shear stress - shear rate hysteresis makes the precise control of the ER mechanical devices very ...
