Holographic polymer‐dispersed liquid crystal fabrication under electric field

Abstract

The transmission mode of holographic polymer‐dispersed liquid crystals (HPDLCs) was developed an under electric field. It is reported that orientation of LC molecules under an electric field induces orientation of oligomer molecules giving rise to low off‐state diffraction and small grating shrinkage.

A review of the electro-optical properties and their modification by radiation in polymer-dispersed liquid crystals and thin films containing CdSe/ZnS quantum dots

“…The PDLC-based periodic structures (HPDLCs), which can be fabricated by using holographic techniques, exhibit even more interesting electro-optical properties, and they too are the basis for many advanced optical devices, like switchable holographic gratings (SHGs) and photonic bandgap structures [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50]. Since these devices respond to electric fields (as we show in subsequent paragraphs), their performance is sensitive to external parameters that can affect the internal electric field within the device.…”

Holographic Polymer‐Dispersed Liquid Crystals: Materials, Formation, and Applications

“…Smaller shrinkage is expected to reduce the shear force, thus decreasing the polarization dependence of H-PDLCs. Researchers have shown that small shrinkage could be obtained when a weak electric field was applied on the material film during the fabrication [158]. This is a good way to reduce the polarization dependence although the researchers didn't discuss it in their paper.…”

Phase separation structure and interfacial properties of lattice‐patterned liquid crystal–polymer composites prepared from multicomponent prepolymers

“…Liquid crystal (LC)–polymer composite systems have received great attention because of their potential in modern applications including membranes, display devices, memory storage and holographic devices owing to their intrinsic physical properties . LC–polymer composites possess both the unique self‐assembly properties of a mesogen and the robust physical properties of a polymer matrix and have therefore been widely studied and used for flexible displays .…”
