Preparation of Progressive Driving Bilayer Polymer-Dispersed Liquid Crystals Possessing a PDLC-PVA-PDLC Structure

“…As a common electro–optical material, polymer-dispersed liquid crystals (PDLC) consist of the polymer substrate and micro or nano-sized liquid crystal (LC) droplets embedded in it [ 1 ]. Without voltage being applied, the PDLC exhibits an opaque state due to the random orientation of the LC microdroplets in the polymer substrate [ 2 ]. As a large voltage is applied, the PDLC film appears in a transparent state with high transmittance due to the alignment of the LC microdroplets along the direction of the electric field [ 3 ].…”

The effect of high dielectric BaTiO3 nanoparticle dimensions on the dielectric properties and electro-optical performance of polymer dispersed liquid crystal films

“…10 However, they also exhibit drawbacks, including high operational voltages ranging from 60 to 150 V, reduced light transmission, and off-axis haze. 11,12 To enhance their electro-optical characteristics, various nanoparticles have been incorporated into PDLC films through doping, including quantum dots, 13,14 graphene-like carbon materials, 15,16 magnetic nanoparticles, 17,18 oxide nanoparticles, 11,19–21 and other functional nanoparticles. 22–24…”
