The scattering dispersion of the E7-based SLC films as a function of the temperature of polymerization. The transition temperature for the E7 liquid crystal is . Those cells prepared at a lower temperature have higher scattering and their characteristics belong to the lower brunch of the transmittance curves. The scattering is much lower for the cells polymerized at a higher temperature than . The measurements were done before application of any shearing stress.
The dependencies of transmittance of the 5CB-based SLC and the liquid crystal ordering (insertion) on the wavelength of the probe light and different distance of shearing.
Static electro-optic response of the SLC cell: (a) the dependence of transmittance of the SLC cell vs applied voltage measured between crossed polarizers; (b) corresponding change of the phase retardation vs applied voltage.
Dynamic response of the SLC cells: (a) the dependence of transmittance of the SLC cell on time after switching-off the ; (b) relaxation of the corresponding phase retardation change when the applied voltage drops from .
