Role of BaTiO₃nanoparticles on electro-optic performance of epoxy-resin-based PDLC devices

Pseudopeptidic Polymer Microsphere-Filled Liquid Crystals as High-Performance Light-Scattering Switches

“…The relaxation process (after removal of the field) involves the contribution from the surface (LC−polymer interface) as well as from the volume of LC. 7,49 The intensity behavior in Figure 7b shows, for PF L -5CB and PF M -5CB, it is a single-step reorientation (the major contribution is volume because of the lesser interface area). In contrast, for PF H -5CB, it is a two-step process (contribution of surface and volume both).…”

Recent Advances in The Polymer Dispersed Liquid Crystal Composite and Its Applications

“…Other inorganic NPs such as ZnO, MgO, CuO, BTO, BaTiO 3 , Fe 3 O 4 , TiO 2 [ 76 , 77 , 78 , 79 , 80 , 81 , 82 ] were doped into PDLCs and a decrease in driving voltage was observed. It was found that these particles tended to impact the dielectric constant of the medium or created local field effects which consequently lowered the driving voltage.…”

Polymer-dispersed liquid-crystal-based switchable glazing fabricatedviavacuum glass coupling

“…The incorporation of SiO 2 nanoparticles (NPs) increases the viscosity of the PDLC mixture to improve the uniformity of the lm thickness in the coating process. [27][28][29]31 Moreover, NPs speeded up the curing process, as NPs play a role of a scattering center for UV due to the refractive index mismatch between the NP and the monomer.…”

“…Although small-sized PDLC glass with high transmittance has been prepared by other groups using an injection process or capillary action, these methods are limited to a small-sized cell and are not scalable. [27][28][29] We demonstrated a PDLC glazing with an area of 15 Â 15 cm 2 using wire-bar coating and coupling in a vacuum, preventing the formation of air bubbles in the PDLC device.…”
