Abstract

A new metallomesogen (MOM) was prepared aiming to the realization of liquid crystalline materials. A traditional Polymer Dispersed Liquid Crystal (PDLC) has been considered as a reference point in order to compare it with an other one obtained with the inclusion of MOM. We analyzed the thermo- and electro-optical properties of the reference PDLC and of MOM based PDLC. We focused our attention on the light transmittivity when an electric field is applied to the sample and evaluated the contrast ratio of both materials. Furthermore, a detailed morphological analysis is performed to better understand their behavior. A comparison between the PDLC with and without MOM is presented. Our experimental results demonstrated the possibility to use MOM in order to improve the transmittivity characteristic as a function of an electric field for application such as displays or windows.
