摘要:
A liquid crystal display device comprises a layer of liquid crystal material (3) between spaced-apart cell walls (1,2), and electrodes (5) provided on at least one cell wall for applying an electric field across at least a part of said liquid crystal material. The liquid crystal material has anisotropic light-absorbing particles dispersed therein and substantially aligned therewith. The invention also provides a composition for use in the display.
摘要:
The present invention provides a cholesteric liquid crystal color filter including partition walls that are formed at pixel boundaries, produced by: forming a liquid crystal layer comprising a cholesteric liquid crystal composition including at least a liquid crystal compound, a photoreactive chiral agent and a polymerization initiator; and irradiating the liquid crystal layer with UV light having wavelengths to which the polymerization initiator is photosensitive through a photomask to form the partition walls at areas corresponding to the pixel boundaries while the liquid crystal layer is in an isotropic liquid state or in a cholesteric state not exhibiting selective reflection of light in the visible range. The invention also provides a process for producing a cholesteric liquid crystal color filter including openings that are formed at positions corresponding to at least contact holes and/or electrode lead-out portions.
摘要:
Particles, especially colloidal particles, comprising an interior phase of a non-lamellar reversed cubic, intermediate or hexagonal liquid crystalline phase, or a homogeneous L3 phase, and a surface phase of a lamellar crystalline or liquid crystalline phase, or an L3 phase. A method of preparing such particles by creating a local dispersible phase, within the homogeneous phase, preferably by means of a fragmentation agent, and fragmentating the homogeneous phase so as to form said surface phase. Several medical as well as non-medical uses of the particles referred to, e.g. as an antigen-presenting system, as a delivery system for anticancer, antifungal and antimicrobial drugs, and as carriers of nucleic acids or nucleotides.

Disclosed are a plurality of particles having a narrow particle size distribution, a processes for forming the same, and films containing the same. The plurality of particles, includes one or more discrete polymer shells, wherein at least one of the polymer shells is crosslinked with at least one monomer containing two or more double bonds polymerizable by free radical means; and a core material encased in the polymer shells, wherein the plurality of particles have a polydispersity of from 1.3 to 1.0.
摘要:
A method of forming a nanoporous membrane includes preparing a solution of a gemini Imidazolium Lyotropic Liquid Crystal (LLC) monomer, a polar low-volatility organic solvent, and a radical photo-initiator in a volatile organic solvent; solvent-casting the solution onto a porous material, evaporating the volatile organic solvent; heating such that the gemini imidazolium monomer forms a Q-phase material and photopolymerizing the imidazolium monomer by exposing the radical photo-initiator to UV light; and exchanging the polar low-volatility organic solvent. Also disclosed is a membrane composed of polymerized gemini imidazolium LLC monomers, and a thin- film composite membrane having the Q-phase material supported on a porous supporting membrane.
