Özet
In this study, the electro-optical and phase transition properties of 4-cyano-4′-n-pentylbiphenyl (5CB)liquid crystal doped by various polymers have been investigated. New liquid crystals were synthesized by doping 5CB liquid crystal with various dopants. Dielectric anisotropy properties of the liquid crystals were defined using Capacity-Voltage measurement method. It is seen that dielectric-anisotropy properties of the liquid crystals give different values for different dopant. Phase-transition properties of the samples were investigated with stable temperature method. It was seen that the dielectric properties of the liquid crystals increased with temperature also phase transition peak was observed. In addition, electro-optic phase transition properties of the liquid crystals alter with doping.
