Phase Morphology in Liquid Crystals Mixtures

Investigations on the phases of Cholesteryl and nematic binary mixtures with varying concentrations were carried out using Fabry Perot Scattering Studies (FPSS), Differential Scanning Calorimetry (DSC), and Polarizing Microscopy Studies (PMS). Structural analyses were performed by the Fourier Transform Infra Red (FTIR), spectroscopy, absorptions spectra from Ultraviolet Visible (UV) and Refractive Index (RI). The concentration of the cholesteric and nematic compound proved to have significant effect on the phase transitions, resulting in the appearance of new mesophases. The new transition temperature obtained from FPSS measurements agree well with the PMS and DSC.
