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).
