Abstract

Described herein are liquid crystal compositions that can allow for the adjustment of their refractive indices by the application of an electric field. Also described herein are liquid crystal mixtures containing these compositions. In addition, selectively dimmable reverse-mode polymer dispersed liquid crystal (PDLC) elements and devices using these compositions are also described, which are transparent when no or low voltage is applied and opaque when a voltage or high voltage is applied.
