Abstract

Using a number of techniques, investigations have been carried out for different systems of sample combinations according to varying components and different concentrations of polymer dispersed liquid crystal (PDLC) (Cholesteryl Pelargonate (CP)+ polymer of methyl metha acrylate (PMMA)) in different proportions with ZnO, Fe2O3 nanoparticles and Multi walled carbon nano tubes(CNT). The Phase Transition Temperatures (PTTs) were found using the Fabry- Perot Scattering Studies (FPSS). The textures and the PTTs of pure CP have been studied using the supplementary techniques of Differential Thermal Analysis (DTA) and Polarizing Microscopy Studies (PMS). The results of the above investigations are being presented here. A comparative study between the systems has done; with the addition of ZnO, Fe2O3 showed that a change in the PMS textures indicating a change in the birefringence properties. Further, the clearing temperature also varied with different concentrations of ZnO, Fe2O3 in the mixture of CP + PMMA; the clearing temperature was fluctuating with increasing concentrations of doping particles (ZnO, Fe2O3). The absorption of the sample in the visible range was found using Ultra-Violet visible spectroscopy (UV-VIS). The infrared absorption was also studied using Fourier Transform Infrared (FTIR) spectroscopy.
