Voxelated liquid crystal elastomers
A shape-programmable liquid crystal elastomer comprises polymerized, nematic monomers. The monomers are organized into a plurality of voxels with each voxel having a director orientation.
Optical isomer
The problem that the present invention is to solve is to provide an optical film that has less alignment defects and is less liable to cause variation in the optical characteristics when placed in a high temperature state. The present invention provides an optical film containing a structural unit derived from a specific compound, that is, an optical film containing a structural unit derived from a compound represented by the general formula (I), which has less alignment defects and is less liable to cause variation in the optical characteristics when placed in a high temperature state, and also provides a display device including the optical film.
Methods of making voxelated liquid crystal elastomers
A method of making a shape-programmable liquid crystal elastomer. The method includes preparing an alignment cell having a surface programmed with a plurality of domains. A cavity of the alignment cell is filled with a monomer solution. The monomers of the monomer solution are configured to align to the surface of the alignment cell. The aligned monomers are polymerized by Michael Addition. The polymerized monomers are then cross-linked to form a cross-linked liquid crystal elastomer. The cross-linking traps monomer alignment into a plurality of voxels with each voxel having a director orientation.
TUNABLE FILM APPARATUS
A tunable film apparatus is provided. The apparatus includes: first and second layers; a tunable liquid crystal layer disposed between the first and second layers; and a tuner configured to tune the liquid crystal layer to adjust a light diffusing angle of the tunable liquid crystal layer.
Fluorine-containing liquid crystal elastomer and preparation method and use thereof
The present invention provides a fluorine-containing liquid crystal polymer of Formula (1). The present invention also discloses a fluorine-containing liquid crystal elastomer, which comprises a copolymer of a fluorine-containing liquid crystal polymer of Formula (1) with a near-infrared dye of Formula (2). The fluorine-containing liquid crystal elastomer of the present invention shrinks due to the photothermal conversion effect of the material under the irradiation of near-infrared light, and thus is widely applicable to the field of actuators. The fluorine-containing liquid crystal polymer of the present invention introduces fluorine-containing segments into the cross-linked network of the liquid crystal polymer, to improve the mechanical performance of the material, and greatly extend the service time of light-controlled actuators.
