Abstract:  The characterizations of Schiff base Liquid Crystalline compounds N-(p-n-hexyloxy benzylidene)-p-n-octylkoxy anilines (6O.O8), N-(p-n-hexyloxy benzylidene)-p-n-decylkoxy anilines (6O.O10) and with dispersed 20μl citrate capped Gold (Au) nanoparticles done to observe the changes occurred with the dispersion of nanoparticles in Liquid Crystalline compounds. Liquid Crystalline phases are not disturbed with the dispersion of nanoparticles whereas more advantageous in various applications. The transition temperatures and textures are obtained by using Polarising Microscope (POM) and along with transition temperatures, enthalpy values are obtained from Differential Scanning Calorimetry (DSC). Further Scanning Electron Microscope (SEM) is used to determine the presence and size of the citrae capped Au nanoparticle. Image processing based of gradient measurement technique is also used to identify the transition temperatures.

Keywords: Liquid Crystal, POM, DSC, Nano-dispersion Image processing.
