The Effect of High-Temperature Liquid Crystal on Haze and Voltage Improvements of Dye-Doped Polymer Dispersed Liquid Crystal Film

The current commercial PDLC film and glass products are mainly utilized for internal privacy applications.In this work we studied the effect of process line speed on electro-optical properties of model dye-doped PDLC formulations consisting of high-temperature and standard liquid crystal materials.The results indicated that, in comparison to standard PDLC, the high-temperature PDLC exhibited a significantly lower on-state haze and switching voltage.This study provides a road map for further systematic studies on external applications of PDLC smart glass.
