摘要:We report the determination of refractive indices of polymer dispersed liquid crystal composite withinvisible spectral range 404-706nm for various temperatures. The droplet domain formation effect in polymer liquidcrystal composite system with variation of different polymer dispersed in liquid crystal and pure liquid crystal has beenstudied. The optical parameters due to scattering by sapphire prism have been measured for pure liquid crystal andpolymer dispersed liquid crystal. It is found that the optical anisotropy of polymer dispersed liquid crystal compositesystem is greatly changed by polar order present in the polymer droplet environment. The scattering is due to bothreorientation and thermal effects. The wavelength and temperature dependent refractive indices are fundamentallyinteresting and practically important for optimizing display performances and other photonic devices employing LCssuch as high temperature gradient LCs, high thermal tunable LCs, and photonic liquid crystal fibers.
