摘要

提出了一种同时测量电流变流体在剪切和电场联合作用下的流变和光学响应的方法。商业电流变流体的流变光学结果显示，在流变响应的时间范围内，施加电场时发生的微观结构变化。值得注意的是，需要更多的证据来验证或反驳粒子颤动是内质网活性所必需的基本潜在机制。制备了一种新型流体，其中分散的颗粒是微胶囊，具有聚苯乙烯壁和主要的水芯。这些流体具有er活性，未来将用于独立研究界面和体极化模式

A rheo-optical and materials approach to electrorheology

A technique was developed to measure simultaneously the rheological and optical response of electrorheological (ER) fluids in combined shear and electric fields. Rheo-optical results for a commercial ER fluid exhibit microstructural changes occurring upon application of an electric field that are well within the time frame of the rheological response. It is noted that additional evidence is needed to verify or refute particle fibrilation as the fundamental underlying mechanism necessary for ER activity. Novel fluids in which the dispersed particles are microcapsules with a polystyrene wall and primarily water core have been prepared. These fluids are ER-active and will be used in the future to investigate interfacial and bulk polarization modes independently.<>
