Research Abstract

A new system has been introduced which has succeeded in clearly observing the three-dimensional structure of immiscible polymer blends. Without shear flow, droplet coalescence and column formation were clearly observed. Under shear flow subjected to a step electric field, on the other hand, a structural change was observed from a droplet-dispersed phase to a network one. It was shown that the shear stress can be described in terms of the interface tensor.
