Temperature-dependent electro-optical and elastic properties of carbon nanotube doped polar smectogen octylcyanobiphenyl

Synthesis, thermal, dielectric and electro-optic properties of new series of fluorinated hydrogen-bonded liquid crystals

“…For example, it decreases from 1.7 for 7OBAF/8OBA to 1.3 for 10OBAF/8OBA. Similar behavior has been observed in other nematic LCs; for example, Δε of 5CB (Δε = 12) [37] is higher than that of 8CB (Δε = 8.5) [38,39].…”

“…K11 and γ for 7OBAFF/8OBA were much higher than other complexes and quickly varied with the temperature in the lower temperature range of the nematic phase. Interestingly, γ of the present mixtures were much lower than that of the individual compounds 8OBA and other calamitic nematic LCs, for example 5CB [37] and 8CB [39].…”

Adsorption from Binary Liquid Solutions into Mesoporous Silica: A Capacitance Isotherm on 5CB Nematogen/Methanol Mixtures

“…Spatial confinement of liquid crystals can alter their physico-chemical properties substantially. Novel phase behaviour, complete suppression of phase transitions and inhomogeneous structures and dynamics have been reported experimentally and validated both by analytical theory and computer simulation [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. In particular the advent of porous media with tailorable pore shapes and tuneable pore size from the macro-, via the meso-to the microscale have resulted in an increased number of studies aimed at an understanding of liquid crystalline behaviour in these interface-dominated geometries [1,11,[15][16][17].…”
