摘要： This disclosure outlines a new method of modifying the properties of existing liquid crystals by doping them with ferroelectric micro- and nanoparticles. We show that this approach, in contrast to the traditional time consuming and expensive chemical synthetic methods, enriches and enhances the electro-optical performance of many liquid crystal materials. We demonstrate that by changing the concentration and type of ferroelectric particles the physical properties of the nematic, smectic, and cholesteric liquid crystal materials can be changed, including the dielectric constants, the birefringence, the phase transition temperatures, and even the order parameter. We also demonstrate the performance of these new materials in various devices, including displays, light modulators, and beam steering devices.

摘要： A new light modulating material using unidirectionally oriented micro-domains of liquid crystal separated by polymer chains is provided. Liquid crystal/polymer films are produced by a one step production process involving a photopolymerizable monomer mixed with a liquid crystal then exposed to UV light. In one embodiment, force deformations are applied to the films resulting in diffraction efficiencies of more than 95%. In another embodiment, applying a planar force to a thick film that produced a 2 μm shift of phase retardation in several hundred microseconds when an appropriate field is applied. Use of this invention provides fast response time and a low required driving voltage. The new cell can be used as spatial light modulators for manufacturing information displays, electro-optical devices, telecommunications system, optical data processing, adaptive optics applications, color projection displays and switchable micro-lens optics.
