Comparative study of nanoparticles doped in Liquid Crystal Polymer System

A comparative study of three nanoparticles Zn, ZnO and CuO doped in Nematic Liquid Crystal Polymer System (NLCPS) with different concentration was studied. The NLCPS combines the orientational ordering properties of liquid crystals, polymer and nanoparticles. The investigations were performed using Polarizing Microscopic Studies (PMS) and Fabry Perot Spectroscopic Studies (FPSS). After doping Zn, ZnO and CuO nanoparticles with liquid crystal polymer system, the response was studied at high temperature. The phase transition temperatures obtained by FPSS were confirmed by PMS. LCPS is useful for displays and may also be used for tunable wavelength filters, tunable liquid-crystal lenses and polarization-independent phase modulators.
