1B17 Analysis of Vapor Pressure of Binary Liquid Crystal Mixture Using Regular Solution Theory

Abstract

The vapor pressures of binary nematic liquid crystal mixtures were investigated by means of regular solution theory, which is one of the thermodynamic treatments for non-ideal systems. Solubility parameters were used to estimate the activity coefficient for liquid crystal solution. As a result, it is not worth while to attempt to correct the vapor pressures of liquid crystal mixtures for deviations from Raoult's law in vapor pressure-composition curves.
