Optical model to describe coherent transmittance of polymer dispersed liquid crystal film doped with carbon nanotubes

An optical model has been developed for analyzing the coherent transmittance of a polymer dispersed liquid crystal films doped with carbon nanotubes (CNTs) at uniform normal droplet-polymer interface anchoring. It is based on the Foldy-Twersky and anomalous diffraction approximations, Maxwell-Garnett equations, and the order parameters concept. The model allows one to analyze the electro-optical response of films depending on their thickness, the refractive indices of the liquid crystal (LC) and polymer matrix, size and concentration of the LC droplets, concentration of nanotubes, conductivities of the LC and the polymer. Experimental verification of the model is performed. (C) 2020 Elsevier Ltd. All rights reserved.
