    摘要: Briefly, according to one aspect of the invention, liquid crystal material is microencapsulated by a method utilizing an interfacial polymerization reaction which creates a combination of polyurethane and polyurea polymers which form the capsule walls surrounding the discrete liquid crystal droplets. The formed capsule walls are designed to have an adjustable refractive index so as to allow for the matching of the refractive index to that of the liquid crystal and polymeric binder materials. This allows for the production of a liquid crystal droplet surrounded by polymer film, which is optically clear when the liquid crystal director is aligned with the electric field. The microencapsulated liquid crystal droplets improve the dye stability of a dichroic dye and enhance the contrast of a liquid crystal display.
