| 摘 要： | 选用CeCl4和FeCl3等对自制的对苯撑进行掺杂，将制得的高介电聚苯撑粉末加入到硅油中得到电流变体流体，测量了在电场作用下粘度和漏电流密度，以及相关的物理常数。讨论了电场强度、粒子浓度与粘度和漏电流密度的关系，粘度变化的响应速度和恢复时间，并探讨了其相关机制。

| Abstract: | Polyparapheneylene (PPP) was doped by CeCl 4 and FeCl 3, and then electrorheological (ER) suspensions were prepared by polymer powder with high dielectric constants and silicone oil. Under electric field, the change of viscosity, leakage current density and relative physical constants were measured. The relationships among electric field strength, particle concentration, viscosity and leakage current density were discussed. The speed of electrorheological response and the recovery time were studied and corresponding mechanisms were investigated. |
