An investigation is described on the electric-field-induced structures in colloidal dispersions. Both rheological determinations and direct microscopic observations are used with that aim. The starting point of this study is the so-called electrorheological (ER) effect, consisting of the mechanical reinforcing of a fluid or suspension due to formation of chains of molecules or particles after being polarized by the action of the field. One macroscopic manifestation of this phenomenon is the… Expand
Effect of surface properties on the electrorheological response of hematite/silicone oil dispersions.
A "negative ER effect" was observed for hydrophobically modified (oleic acid coated) hematite, which means that the field produces destruction of structures rather than their build up, above a threshold electric field strength. Expand
Surfactant-Switched Positive/Negative Electrorheological Effect in Tungsten Oxide Suspensions
The negative electrorheological effect was shown to be associated with the processes of phase separation in the electric field, which led to a multiplicative effect and a strong electroconvection of the suspension at field strengths above 1 kV/mm. Expand
Negative electrorheological responses of mono-dispersed polypyrrole-SAN copolymer suspensions
AbstractThe mono-dispersed polypyrrole (PPy)-poly(acrylonitrile-co-styrene) (SAN) copolymer particles were synthesized by emulsion polymerization and the electrorheological (ER) behavior of theirExpand
Electric field induced gelation in aqueous nanoclay suspensions.
The electric field induced LAPONITE® soft solids demonstrate all the typical rheological characteristics of soft glassy materials and are mechanically stronger and more stable over longer periods of time than salt induced gels studied here. Expand
Positive and negative electrorheological response of alginate salts dispersed suspensions under electric field.
The specific salt type of biomacromolecules could be suitable ER particles for negative ER suspension for the first time, and can present a new way for the development of the biocompatible and eco-friendly negative ER fluids. Expand
The negative and positive electrorheological behavior and vibration damping characteristics of colemanite and polyindene/colemanite conducting composite
In this study, the electrorheological (ER) properties of colemanite and polyindene (94.8% PIn)/colemanite (5.2%) conducting composite were investigated by dispersion in silicone oil (SO). The zetaExpand
Electrorheology of clay particle suspensions. Effects of shape and surface treatment
AbstractWe investigate the electrorheological (ER) properties of clay (montmorillonite, sepiolite, and laponite®). The selected clays allow to distinguish between planar particles of different sizesExpand
Preparation of Smart Fluid from Polymer Coated Pumice Particles
This study reports, electrorheological (ER) responses of pumice and poly(methyl methacrylate)/ pumice, PMMA/pumice, conducting composite dispersions in silicone oil (SO). Primarily three differentExpand
Design of negative electrorheological materials inspired by electrophoretic separation of biomolecules
Inspired by the electromigration phenomenon in biomolecules, we fabricated various oligoamine-modified polyacrylonitrile (PAN) particles to aim for a negative ER effect. A noteworthy result is thatExpand
Electrorheological response of polyindene/colemanite conducting composite
In this study, electrorheological (ER) responses of colemanite and polyindene (PIn)/colemanite conducting composite dispersions in silicone oil (SO) were investigated. Antisedimentation ratios of theExpand
