TERNARY LIQUID CRYSTAL COMBINATION HAVING COMPLICATED E7/6CB/6BA ELECTRO-OPTICAL, THERMAL, AND DIELECTRIC CHARACTERISTICS

Abstract

In this work, a new liquid crystal mixture complex was devised 
and synthesised using the nematic liquid crystal mixture E7, 
hexylcyanobiphenyl (6CB) and hexylbenzoic acid (6BA) (6BA). 
The thermal and morphological characteristics were studied by 
differential scanning calorimetry (DSC) and polarised optical 
microscopy (POM) (POM). The DSC and POM data demonstrate 
that the liquid crystal complexes display liquid crystalline 
qualities with smectic and nematic phase. While the E7 ratio is 
80 percent , the mixed complex has the broadest nematic range 
and shows E7 features. When the E7 weight ratio is less than 80 
percent , with the creation of hydrogen bonds the number of 
mesogenic phases rises and the nematic range declines. The 
electrical characteristics of acquired samples were examined 
using impedance spectroscopy method. The birefringence and 
contrast ratio of samples also studied with the assistance of light 
transmittance experiment.
