It has been shown in electrorheology that filtration occurs and that it impacts the structuring and rheology of electrorheological fluids under an electric field. This paper demonstrates the impact of filtration on the mechanical properties of these

Dispersions of various concentrations (15-35%) were prepared in silicone oils of vastly different viscosities (40, 1000, 10,000, and 30,000 mPa s) and compressed to high values of stress while under an electric field of 2 kV/mm. A purpose of this stu

The effect of high ac electric fields upon a liquid crystalline polymer solution, poly(n-hexyl isocyanate) in p-xylene, is examined. The results show that the solutions exhibit an increase in rheological properties proportional to the strength of the

The effect of a high electric field on a solution of a lyotropic liquid-crystalline polymer, poly(n-hexyl isocyanate) in p-xylene, was studied. The application of a high-voltage alternating-current electric field to the biphasic solution resulted in

The effect of high (1000 V/mm) electric fields on solutions of a lyotropic liquid-crystalline polymer, poly(n-hexyl isocyanate) in p-xylene, is presented. The con- centrations are adjusted such that the solutions are strictly within the isotropic pha

In this article it will be demonstrated that columns of particles bridging the electrodes are not the characteristic feature of ER fluids under field. Instead a higher level of order, particle lamellae, must develop under shear and E field if a suspe

Under static conditions, ER suspensions form columns under electric field. However under the combined stimulii of a shear and electric field, the particles assemble into lamellar structures. The morphology of these structures are complex functions of

It was reported that under the simultaneous stimulus of an electric field and shear, the particles in an ER fluid form lamellar formations in the direction of shear (adhered to one of the electrodes) which may be responsible for the ER activity more

Solutions of polyhexyl isocyanate in xylene, a well known lyotropic liquid crystalline system, are shown to be ER active at concentrations well below those for the onset of a mesophase. This correlates with a field dependent birefringence or orientat

Various base ER fluid compositions are shown to have dramatically enhanced shear stresses when dispersed into poly(hexyl isocyanate)/xylene solutions as compared to being dispersed into polystyrene/xylene solutions. The concentration of the PHIC solu
