Research Abstract

Flow induced structures and those controllability of a smectic liquid crystal and particulate suspensions have been investigated for the development of functional soft materials, as those composition elements. It has been clarified that the strength of complex structures of the liquid crystal generated from electro-convection states is able to control with small strain applied. Moreover, the fluidity of the anisotropic structure generated in the flow of particulate suspensions was adjustable with the application of shear reverse.
