Calculation of Layer Thickness in Smectic A Phase of Binary Mixtures of Terminal Polar + Terminal Non Polar Mesogens

Abstract

The variations of layer thickness with concentration in the smectic A phase of binary mixtures of a terminal polar (A) and a terminal non-polar (B) mesogens have been calculated and compared with their experimental values for eight different mixtures. The calculation is based on assumption regarding formation of AA and AB type dimers in the mixture. The agreements between calculated and experimental layer thickness for all the mixtures are very good.
