Abstract
Polyaniline (PAn) as the dispersive particles and insulating oil as the dispersive medium, the electrorheological fluid (ERF) is constituted. Relations between the factors of electric field strength ( E ), temperature ( T ) and the static yield stress ( τ S ), current density ( i ) of ERF are investigated. The results show that the changes of τ S and i with electric field intensity have emerged in the exponential relation, i.e, τ S∝E 0.7 , i∝E 2.18 . Otherwise, when exert a constant voltage on ERF, owing to the polarization, the absorption of medium of ERF have taken place. Therefore, the attenuation rate equation of current can be show as i=(E/R) exp (-t/RC d)
