A Comprehensive Review on Polymer-Dispersed Liquid Crystals: Mechanisms, Materials, and Applications

ACS Materials Au, Год журнала: 2024, Номер 5(1), С. 88 - 114

Опубликована: Ноя. 27, 2024

Polymer-dispersed liquid crystals (PDLCs) stand at the intersection of polymer science and crystal technology, offering a unique blend optical versatility mechanical durability. These composite materials are composed droplets interspersed in matrix polymeric materials, harnessing properties while benefiting from structural integrity polymers. The responsiveness LCs combined with rigidity polymers make polymer/LC composites─where network or is used to stabilize modify LC phase─extremely important for scientists developing novel adaptive devices. PDLCs have garnered significant attention due their ability modulate light transmission properties, making them ideal candidates applications ranging smart windows displays shutters privacy filters. incorporation different ferroelectric, thermoelectric, magnetic, ferromagnetic nanoparticles, quantum dots, nanorods, variety dyes PDLC has gained momentum over span few decades, as it lowers otherwise-required high operating voltage reduces electro-optical response time these Due better contrast transmittance field-off on states, they find extensively wide application photonic applications, viz., windows, photorefractives, modern displays, microlens arrays encompassing polymer-gravel lenses, many other. Since functional parameters devices embrace thermophysical attributes networks, therefore becomes necessary perform detailed analysis ameliorations upon addition dopants. This Review aims review recent advances enrichment terms performance dopants, well improvement owing superior parametric implementation networks.

Study on the Effect of α-Substituted Acrylate Monomers on the Electro-Optical Properties of Polymer-Dispersed Liquid Crystal Films

ACS Applied Materials & Interfaces, Год журнала: 2023, Номер 15(50), С. 58861 - 58872

Опубликована: Дек. 7, 2023

Polymer-dispersed liquid crystals (PDLCs) show great application potential in the areas of displays and smart windows. However, their electro-optical (E-O) properties such as contrast ratio threshold voltage still need further improvement. In this study, effects α-substituted acrylate monomers on morphology E-O PDLC composite films were systematically studied. It was found that large substituent tended to increase void size polymer matrix, while small fluorine substitution led a microsphere-type morphology, which deteriorated performance. Finally, largely improved performance low (0.437 V/μm), saturation (1.012 high (27) achieved an 8 μm-thick film by addition chlorine-substituted monomer. This study provides new approach for optimizing PDLCs from material perspective.
