聚苯胺悬浮液的电流变效应

THE ELECTRORHEOLOGICAL EFFECTS OF POLYANILINE SUSPENSIONS

以掺杂态的聚苯胺为悬浮颗粒，以硅油为分散介质，制得悬浮液研究了它的电流变效应及其影响因素，如电场强度、剪切速率、悬浮液浓度、颗粒介电常数等．还研究了该体系的漏电流密度及其影响因素．实验表明，随着电场强度等的增大，悬浮液的电流变效应增大，同时漏电流密度也增大；而随剪切速率的提高，电流变效应及漏电流密度均减弱．

In this paper, the suspensions containing polyaniline particles and silicone oil were propared.The electrorheological effects of these suspensions were studied through steady-state shear, and the currentdensity of the suspension was experimentally investigated as well. The experimental results show that with increasing field strength, the suspension's electrorheological effect and current density increase;while with increasing shear rate, the suspension's electrorheological effect and current density decrease.
