Thermo-optical and electro-optical response of binary mixture of liquid crystalline materials

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.
