Topological transition of an immiscible polymer blend in electric and shear flow fields

The morphology and theology of an immiscible polymer blend under electric and shear flow fields were studied. A transition from a droplet-dispersed structure to a network structure was observed by using a specially designed shearing device and a confocal scanning laser microscope. This was accompanied by a change in viscosity. By digitally processing captured serial images in steady states at different shear rates and electric fields, we found scaling properties.
