Improved dielectric and electro-optical parameters of ZnO nano-particle (8% Cu2+) doped nematic liquid crystal
چکیده انگلیسی

Properties of nematic liquid crystal can be improved by doping of nano-particle. Dielectric and electro-optical parameters have been determined in the present paper, to understand the effect of 8% Cu2+ doped ZnO nano-particles in the pure nematic liquid crystal (NLC). The magnitude of dielectric anisotropy was found to increase in negative order and in turn it reduces the response time for nano-nematic composite system. However the threshold voltage has shown an increase for this composite system. The splay elastic coefficient, rotational viscosity and other parameter have also shown improvement. All the results i.e. related to the determination of dielectric and electro-optical parameters have been well explained by using existing theory of NLC.


► The addition of nano particle in nematic liquid crystals, to improve the electro-optical parameters.
► The response time is also sensitive to the influence of nano particle in nematic liquid crystals.
► The doping of nano particle has caused variation in almost all the properties of the NLC.
