Thermo-optical and electro-optical response of binary mixture of liquid crystallinematerials

Author(s): T.N.Govindaiah

We report the results of our studies on the optical, thermal and elctrooptical properties of binarymixture of cholesteric and nematic compounds: namely, p-butoxybenzylidene, p-heptylaniline (BBHA) and cholesteryl nanonate (CN). The mixture exhibits very interesting twisted grain boundary (TGB) phase and re-entrant smectic-C (ReSmC) phases sequentially when they are cooled from its isotropic melt. Optical and electro-optical studies have been discussed.
