“…Based on the above features, PDLC has been widely used in smart windows [ 4 , 5 , 6 ], displays [ 7 , 8 ], and optical switches [ 9 , 10 , 11 ]. Furthermore, PDLC is favored in low energy-consuming buildings [ 12 , 13 , 14 ], semiconductors [ 15 ], field-effect transistors [ 16 ], and solar concentrators [ 17 ].…”

Using the polymerization-induced phase separation (PIPS) method, bilayer polymer-dispersed liquid crystal (PDLC) films with a PDLC-PVA-PDLC structure were prepared in this work. It was found that all PDLC performance indexes were affected by polymer mesh size after comparing the microscopic morphology and electro-optical properties of samples with different monomer ratios. Gd2O3 nanoparticles and rhodamine B base fluorescent dyes introduced into the bilayer PDLC optimized the samples’ electro-optical properties and developed new functionalities. In addition, the bilayer PDLC doped with Gd2O3 and rhodamine B base held excellent progressive driving functions as well as stable durability properties. Samples doped with Gd2O3 nanoparticles and rhodamine B base also produced excellent anti-counterfeiting effects under UV irradiation at different angles, further exploiting the application potential of PDLC.

In this paper, the bilayer polymer-dispersed liquid crystals possessing a PDLC-PVA-PDLC structure were prepared by integrating two monolayer PDLCs. The effect of the polymer mesh size on the electro–optical properties of a bilayer PDLC was investigated by comparing the micro-morphology and electro–optical curves under different polymerization conditions. In addition, the impact of doping MoO2 nanoparticles with surface modification on the comprehensive performance of the bilayer PDLC was further researched. The contrast ratio of the bilayer PDLC prepared under the optimal conditions was improved by more than 90% and still maintained excellent progressive driving performance. Therefore, the development of a bilayer PDLC with optimal electro-optical properties will significantly enhance the technological prospects for the application of PDLC-based devices in smart windows, displays, and flexible devices.

“…In regions with warm climates, an excessive amount of glass in buildings can lead to significant heat gain and visual discomfort. Consequently, current commercial smart glazing systems like polymer-dispersed liquid crystal (PDLC) [30], electrochromic (EC) [13], and suspended particle device (SPD) [31] glazing are deployed to enhance indoor thermal and visual comfort. Compared to low-emissivity (low-E) double glazing, SPD smart windows have the potential to reduce net energy consumption by up to 58% [31].…”

Glazing systems play a significant role in managing the interaction between indoor and outdoor temperatures within a building. This research was conducted in a laboratory at Najran University in Saudi Arabia, focusing on six different glass samples, including two conventional (double low-E glass and vacuum clear glazing) and four smart glazing configurations (PDLC and SPD in both ON & OFF states), aiming to analyze their impact on indoor-outdoor temperature interaction, solar radiation control, and visual comfort. Key findings include SPD-OFF's superior temperature control (limiting increase to 24.28℃ compared to 10.53℃ for double low-E), PDLC-ON's optimal daylight illumination (2901.43 lux), and its higher energy efficiency (97.97 W/m² heat gain) compared to 44.8 W/m² for double low-E. The study also highlighted cost and environmental differences, with double low-E being the most cost-effective ($1.43/m² ) and PDLC-ON the most eco-friendly (14.5 kg CO2/m² ), despite higher operating costs. Overall, smart glazing systems, particularly the PDLC configuration, demonstrated notable advantages in thermal and visual comfort management.
