| Abstract | ||
| The importance of the compounds which have liquid crystalline properties comes from its uses in a lot of practical applications; therefore the study of its electrical properties and the effect of the nanoparticles on its electrical properties are considered one of the most important things. In this study many of organic compounds have been prepared and then diagnosed by using the IR spectroscopy (FT-IR), and the differential scanning calorimeter (DSC) and also the Polarized light microscopy. And then we selected two compounds that possess liquid crystalline properties and we made a combination of the bilateral system, and we got the less temperature at a concentration of (53% A).This combination of the bilateral system diagnosed by using the differential scanning calorimeter (DSC) and Polarized light microscopy. Silver nanoparticles have been prepared and then diagnosed by x-ray diffraction (XRD) and the Scanning Electron Microscopy (SEM) and also the Atomic-force microscopy (AFM). The addition of silver nanoparticles by mixing of a certain percentage from it with the mixture of the bilateral system at the construction of (53% A) plays an important role in the changing of the electrical properties of the bilateral system mixture, for this reason the silver nanoparticles has been chosen in this research to study the effect of adding it to the mixture of the bilateral system, on the electrical properties of the mixture. We noticed through the LCR meter an increasing of the electrical conductivity of the mixture by the existence of silver nanoparticles in a concentration of (53% A). | ||
