In this study, electrorheological behavior of suspensions prepared from 0.9 and 5.0 µ m calcium carbonate particulates, dispersed in insulating silicone oil medium was investigated. Sedimentation stabilities of suspensions ( c = 5 wt %) prepared using these calcium carbonate powders were determined to be 6 and 4 days, respectively. Electrorheological activity of all the suspensions was observed to increase with increasing electric field strength, concentration and decreasing shear rate. Shear stress of calcium carbonate suspensions increased linearly with increasing concentrations of the particles and with the applied electric field strength. Electric field viscosity of all the suspensions was decreased sharply with increasing shear rate and particle size, showing a typical shear thinning non-Newtonian visco-elastic behavior. Effects of elevated temperature and polar promoter onto electrorheological activity of calcium carbonate/silicone oil system were also investigated.#

Electrorheologically intelligent polyaniline and its composites

Electrorheological (ER) fluids are generally composed of electrically polarizable inorganic or organic particles dispersed in insulating oils. These materials are intelligent/smart materials in that they are capable of changing their state from liquid-like to solid-like very quickly under an applied electric field. This feature article reviews the literature regarding the fabrication of conducting polyaniline (PANI) and PANI composite particles, their ER performance, as well as their chemical and physical characteristics of morphology and crystal structure. The ER behavior of these intelligent materials was also analyzed using a range of rheological equations of state and their dielectric properties.

“…Fibrillation of this ER fluid was observed directly by OM under an applied electric field produced by a DC high-voltage source [29]. Initially, the PMMA-PNMA particle-based ER fluid was injected between two electrodes (∼350 m) without an electric field, as shown in Fig.…”
