Electrorheological Response and Structure Growth of Colloidal Silica Suspensions

Electrorheological response of modified silica suspensions

“…8 The dielectric constant of the particle ε p was estimated from that of the suspension by a volume average calculation 9 given by equation ε r = ε p φ + (1 − φ)ε L where φ and ε L are the volume fraction of the powder in the suspension and the dielectric constant of the fluid (silicone oil).…”

“…Among them silica particles dispersed in silicon oil. [6][7][8] In this paper, we are investigating the effect of some metallic cations on the silica structure and its ER behaviour when mixed with silicone or organic oil. * Corresponding author.…”
