Change of mesogenic properties of liquid crystal 5СB at the presence of silver nanorods


Influence of silver nanorods on mesogenic properties of nematic liquid crystal 4- cyano-40-pentylbiphenyl (5CB) is investigated by the methods of differential scanning calorimeter, polarization microscopy, and dielectric spectroscopy. It is shown that the temperature of the nematic-isotropic transition increases. In this case, there is a decrease in enthalpy and entropy of the phase transition at presence of silver nanorods.

Keywords: nematic liquid crystal; silver nanorods; polarization microscopy; differential scanning calorimetry; electric conductivity; dielectric permittivity.
