| Research Abstract |
The research purpose is to provide a method of generating viscosity anisotropy in liquids. On the application of high electric fields to suspensions, the particles form chain structures between electrodes and this leads to a drastic viscosity increase. When the suspensions are sandwiched between two pattern electrodes that produce nonuniform electric fields and the asymmetric structures of aggregated particles are constructed, the viscosity and yielding behavior show anisotropic responses. The viscosity anisotropy is also induced by the use of a single flat plate, on which the electrodes of line and space are coated.
