摘要
电流变体是当令智能材料领域的一个研究热点。基于对无机材料硬度高、密度大等缺陷进行改进的目的,合成了二氧化硅/淀粉复合颗粒,对该颗粒的化学组成和粒度、粒度分布进行了测试。同时,对由该颗粒合成的电流变体在直流、交流两种电场作用情况下的流变性能进行了测试。
Electrorheological (ER) fluid is a research focus in today's smart materials and structure. For the purpose of overcoming the disadvantages of inorganic ER materi- als such as the high hardness and density of the dispersed particles, a kind of compo- site particles made from silica and starch is developed. The component, size and size distribution of the composite particles are measured. In the meantime, the rheological properties of ER fluid made of this composite particles are tested. DC and AC electric fields are imposed to ER fluid separately.
