Abstract
Polymer dispersed liquid crystals are functional materials which can enhance optical, electrical, thermal and mechanical properties. These materials have combined applications of liquid crystal in addition to polymer. In the present paper, an effort is made to study the effect of polymer concentration on optical and electrical properties of liquid crystal which was investigated by various characterization techniques. The fabry perot scattering studies were used to investigate optical properties in addition to the phase transition temperature whereas the dielectric and conductivity measurement were done by impedance analyzer. The phase transition temperature for the composite material was found higher as compared to the pure liquid crystal. Our investigation reveals enhancement in strength, proper contrast ratio with good visibility, changes in the orientation of the composite material which provides an opportunity and potential photonics application such as light emitting diode and image sensors.
