| Résumé: | This work consists in preparing mixtures of nematic liquid crystal and inorganic nanoparticles of the 5CB / TiO2 type, the aim of which is to study the variation in the properties of the liquid crystal under the effect of doping. One of the important properties to study is the nematic-isotropic phase transition “TNI”, established by the MOP technique. It has been observed that this temperature varies as a function of the concentration of the “TiO2” dopant which has been synthesized by a Sol-Gel process. However, an investigation into the opacity of these mixtures was followed by UV-visible. Other characterization techniques: FTIR, DRX, DSC were used to analyze these mixtures in order to optimize their applications. |
