Thermo - Optical Studies of Nematic Liquid Crystal Elastomer

摘要

The influences of structural parameter on thermo - optical properties of Nematic Liquid Crystal Elastomer (NLCE) were studied using Differential Scanning Calorimetry (DSC), Fourier Transform Infrared (FTIR) Spectroscopy and Polarizing Microscopy Studies (PMS). Dielectric Measurement was also performed in addition to these measurements. The NLCE used in the present study were synthesized, has a unique coupling between anisotropic order of Liquid crystal component and elasticity of polymer network. The investigations were performed as function of temperature during heating and cooling processes. The study revealed the correlation of thermo - optical behavior of NLCE with the crosslinking agent and temperature.
