We have investigated the structural change of an immiscible polymer blend in shear flow when subjected to a step electric field. During the process three-dimensional images were successfully constructed with a confocal scanning laser microscope and at the same time the transient shear stress was also measured. The interface tensor was calculated from the images. Several factors are incorporated into the shear stress, such as the bulk viscosity, the interfacial tension and the Maxwell stress. We performed an experiment to separate the Maxwell stress from the total shear stress. The results are discussed in terms of the interface tensor.
我们研究了在施加阶跃电场时剪切流中不混溶聚合物共混物的结构变化。在这个过程中，我们成功地使用共焦扫描激光显微镜构建了三维图像，同时还测量了瞬态剪切应力。从图像中计算出了界面张量。将几种因素（如体粘度、界面张力和麦克斯韦应力）纳入到剪切应力中。我们进行了一项实验，以将麦克斯韦应力从总剪切应力中分离出来。结果将根据界面张量进行讨论。
