抜粋

The dissipative structures were irreversibly induced in the nematic composites through a procedure that an electric voltage was applied in the direction perpendicular to the substrate surface of the cell in which the molecules were uniaxially oriented in the plane by rubbing treatment. The striped structure is possibly formed by electrically induced reorientation of directors. We discuss: 1) the applied voltage dependence for the structure formation, 2) the transient behavior of structure formation for composites thorough the evaluation of optical texture and dielectric constant. The resultant periodic structure formation was found on application of 6V electric voltage, which was appropriate voltage to prevent heterogeneous structure formation from mode of nucleation and random reorientation of directors in the composites. The periodicity of the structure was determined in the early stage of the application process of an electric voltage. The resultant dielectric constant and texture indicate that the tilted director of the composites was pinned by polymer after removal of an electric voltage.
