摘要 通过研究TiO2包覆不同极性分子修饰金属Ni核心核壳微粒的结构及其电流变液的性能,分析Ni/TiO2基核壳结构微粒电流变液性能与极性分子种类、复合修饰以及所加电场强度的关系。结果表明,对同成分电流变液随极性分子的加入,其强度均出现不同程度的增加,多层修饰利于电流变液剪切强度的提高,十二烷基苯磺酸钠(SDBS)可显著提高电流变液的沉降稳定性。 Properties and microstructure of electrorheological fluid of Ni particles covered with TiO2 modified by polar molecule were studied.The results show that ER properties of the particles are closely associated with polar molecule and electric field.It is found that shear stress increases with adding polar molecule,multilayer modification can improve the properties of ER fluid,SDBS can enhance sedimentation.
