Abstract: The Liquid Crystalline Nano composites are prepared by dispersing TiO2, ZnO nano particles separately in 4-Cyano-4′ pentyl oxy biphenyl (5O.CB) liquid crystal in the ratio of 1:100. The characteristic textures exhibited by the composites and their phase transition temperatures are recorded by polarizing optical microscope. The Phase transition temperatures are also carried out by Differential Scanning Calorimeter for confirmation. SEM, EDAX, analysis is done for the characterization. By using Modified Spectrometer, the birefringence of Pure and Liquid Crystalline nano composites is measured in nematic phase. The Orientational Order Parameter of liquid crystalline nano composites are estimated by different methods. The results are discussed.
