Electro-optic and dielectric investigations of a perfluorinated compound showing orthoconic antiferroelectric liquid crystal

We observed microsecond order response ranging from 100 to 600 mu s with respect to temperature for a single component fluorinated rigid core antiferroelectric liquid crystals having highly tilted phases. In the antiferroelectric region, we observed V-shaped electro-optic switching in a 4 mu m indium tin oxide coated homogeneously aligned cell having P-S, ranging from 100 to 200 nC/cm(2). Dielectric studies have revealed an interesting phase that exists during heating in the temperature region between 74 degrees C and 84 degrees C. From dielectric results studied we calculated activation energies associated with different relaxation modes using Arrhenius law. (C) 2012 Elsevier B.V. All rights reserved.
