Holographic Polymer-Dispersed Liquid Crystals (H-PDLCs)1
TL;DR: In this paper, the formation of switchable holographic gratings from polymer-dispersed liquid crystals (H-PDLCs) allows for the development of turnable transmissive and reflective diffractive optics, created by coherent interference of laser radiation within a syrup containing photoreactive monomer, initiator, and liquid crystal.

Polymer as an important component of blends and composites with liquid crystals
TL;DR: In this article, a review of various ways of preparation of liquid crystal/polymer blends and composites leading to their required applications is presented. But the most important features of polymers which can be used as components of blends or composites with liquid crystals include: their film formation ability, high transparency, amorphicity, inertness in relation to a liquid crystal, good miscibility with liquid state and immiscibility in a solid state.

Polymerization-Induced Phase Separation. 2. Morphology of Polymer-Dispersed Liquid Crystal Thin Films
TL;DR: In this paper, phase separation in a polymerizing diacrylate/LC mixture is shown to be driven by liquid−gel demixing rather than by liquid −liquid demising, and optical microscopy shows the development of morphology.
