摘要/Abstract

摘要： 将聚苯胺（ＰＡｎ）作为分散粒子，电绝缘油作为分散介质组成电流变流体（ＥＲＦ），研究了电场强度（Ｅ），温度（Ｔ）等因素与ＥＲＦ的静态屈服应力（τＳ）和电流密度（ｉ）的关系．结果表明：τＳ和ｉ随电场强度的变化皆成指数关系（τＳ∝Ｅ０．７，ｉ∝Ｅ２．１８）．而当施加一个恒电压于ＥＲＦ时，由于极化作用ＥＲＦ将发生介质吸收，电流的衰减速度方程可表示为：ｉ＝（Ｅ／Ｒ）ｅｘｐ（－ｔ／ＲＣｄ）

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)

Key words: Electrorheological fluid, Polyaniline particle, Yield stress
