SCATTERING STUDY OF LIQUID CRYSTAL MIXTURES
Journal Title: Journal of Atoms and Molecules - Year 2012, Vol 2, Issue 5
Abstract
It is known that there are two types of liquid crystals, Thermotropic and Lyotropic Liquid crystal. Phase transitions of thermotropic Liquid crystals are very important for many applications. We studied the mixture of Nematic and Cholesteric Liquid crystal at various concentrations. Thermotropic liquid crystal occurs at definite phase transition temperature. In our mixture new mesophases have been detected. Characterisations were carried out on Polarising Microscopic, Fabry perot scattering studies and other techniques. Fabry perot scattering studies is a multiple beam instrument capable of extremely high resolution designed which yields bright fringes on a wide dark background. The diameters of the ring were measured at the various temperatures. Temperatures measured by remote sensing IR thermometer. The Liquid crystal material is actually sandwich between a glass cover slip. It is observed the Phase transition which occur at a known temperature were shifted the transition range, with increase in the concentration.. It is used in display application such as LCD monitor with colour Variation and so many others.
