Abstract
The influence of accelerated ultraviolet (UV) post-curing on the electro-optical (EO) performance of an industrial polymer-dispersed liquid crystal (PDLC) formulation was systematically investigated under production-relevant conditions. Primary curing intensity was varied within 40–200 mW/cm2 range to establish baseline relationships between curing kinetics, morphology, haze (Hon), and switching voltages (V10 and V90). Subsequently, accelerated post-curing treatments were applied on samples cured at 43.2, 106.5, and 162.8 mW/cm2. Increasing primary curing intensity resulted in a near-linear decrease in haze and switching voltages, indicating improved polymer network homogeneity and refractive index matching. In contrast, accelerated post-curing consistently increased normal haze and produced minor but systematic variations in switching voltages.
