Abstract

AbstractThe monomer dispersed liquid crystal is relatively new class of functional materials which has a numerous role in the modern technology. This research work reports the effect of two different concentrations of monomer 2-Ethyl Hexyl Acrylate with on liquid crystals of cholesteryl nonanoate. This monomer is selected due to its low volatile nature and reactivity of double bonds. The thermal behaviour of samples under investigations was studied by differential scanning calorimetry (DSC). The liquid crystal shows a good miscibility with both concentrations of monomer which were confirmed by Fourier transform infrared (FTIR) spectroscopy. The proposed research investigation reveals new phase transitions along with the known phase transitions for this composite system. It was also observed that in the nematic order, the molecules tend to align perpendicular to the surface. This opens a new possibility of this material to be used for variety of new applications like photo-cured network and photopolymer etc.KeywordsMonomerLiquid crystalsCholesteryl nonanoateDifferential scanning calorimetryDielectric spectroscopyFourier transform ınfrared spectroscopyMorphological and thermal Properties
