The effect of liquid crystal concentration on the morphology of few flexible polymer dispersed liquid crystals

Abstract

In this study, we investigated the effect of concentration of TNO623, TNO403 and E43 liquid crystals on the morphology of flexible PDLC films. The PDLC films were prepared on ITO-PET support rolls by Polymerization Induced Phase Separation (PIPS) through UV radiation curing technique. We found that, regardless of the type of liquid crystal and process conditions, the liquid crystal micro-droplet morphology, including the dimensions, number densities and weight fractions, were mostly exhibited the same dependency trends on liquid crystal concentration in PDLC formulation.
