The structure and influence of temperature on mechanical deformation of Liquid Crystal Elastomers (LCEs) were studied using various techniques like Raman Spectroscopy (RS), Fourier Transform Infrared (FTIR) Spectroscopy and Polarizing Microscopy Studies (PMS) etc. The spectroscopic studies confirmed the presence of functional group attached to the sample. The shrinkage in length was observed while heating whereas material returns to its original length on cooling which revealed the correlation of mechanical behavior of Liquid Crystal Elastomers with temperature. This spontaneous shape changing property indicates that LCE material plays an important role in biological applications.

Ferroelectric nano-materials are very sensitive to several external stimuli and have attracted great deal of attention due to their property of improving various properties such as photoluminescence, higher polarization, fast response time, low operating voltage and improved conductivity. For enhancing the physical properties, a proper selection of nano-materials for liquid crystals depends upon various factors such as size, shape, preparation methods, surfactant concentration and amount of doping materials. In the present study an attempt is made to study  electrical and acoustical properties of cholesteric liquid crystal after dispersing ferroelectric nano-powder of Barium Titanate (BaTiO3). In addition with this particle size and surface area of pure and nono-particle dispersed liquid crystal were also measured. Our investigation shows increase in Rao’s constant or molar sound velocity, which indicates increase in molecular density indicating a close packing of the material. The measurement of dielectric relaxation at different frequencies gives information about the dynamics of polar groups and molecular motion.

In the present study, effect of CNT on optical and thermal properties of mixed thermotropic liquid crystal mixture was studied by various techniques to understand their physical behavior. Some new mesophases have investigated by optical methods viz. Polarizing Optical Microscopy (POM) and Fabry-Perot Scattering Studies (FPSS). It has been observed that these new phase transition occur alo ng with the known phase transition temperatures. These new phase transitions corresponding to new mesophases were also confirmed by thermal study using Differential Thermal Analysis (DTA). The CNT doped thermotropic liquid mixtures can be used in various display application such as LCD monitor with color variation to enhance performance.
