摘　　要：聚苯胺基电流变液已有近30年的研究历史,但因本身电导率高导致的漏电密度大、极化能力低、悬浮稳定性差限制了其单独使用的可能,通过化学结构改性或物理共混改性以改善单一组分的性能缺陷是一种有效的改善方法。对聚苯胺进行取代、复合无机或有机粒子可以获得满足商品要求的屈服强度和悬浮稳定性能。归纳了各种聚苯胺基复合材料的制备方法,并分析了其受外场强度、体积含量、环境温度、含水情况等因素影响下的屈服强度、介电性能、悬浮稳定性、粘弹特性、表观粘度等特性,最后总结了聚苯胺基复合材料在电流变研究中存在的问题,提出了今后重点研究的方向。Polyaniline（PAn）-based electrorheological fluid（ERF）has been studied for almost thirty years,while its high electric conductivity leading to intense current density,low polarization ability and bad suspension stability impede its development in ERF.One of the effective ways is to modify PAn according to chemical methods or physical blending.Satisfing yield stress and suspension stability can be obtained by substitution of PAn or composition with inorganic or organic materials.Synthesis methods for various PAn-based materials are decribed.The yield strength,dielectric property,suspension stability,viscoelastic property and apparent viscosity under the effects of electric field,volume,temperature and water content are analyzed.Finally,the key issues and further studies are also pointed out.
