  • Patent number: 10626329
    Abstract: 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.

  • Publication number: 20200115483
    Abstract: Shape-programmable liquid crystal elastomers. The shape-programmable liquid crystal elastomers being synthesized by filling an alignment cell with liquid crystal monomers. The liquid crystal monomers align to a surface of the alignment cell and then are polymerized with a dithiol chain transfer agent. The alignment cell is configured to impose a director orientation on a portion of the shape-programmable liquid crystal elastomer. For some embodiments, liquid crystal elastomer laminates are prepared by arranging a plurality of liquid crystal elastomers such that a director orientation of each liquid crystal elastomer of the plurality is in registered alignment with an adjacent liquid crystal elastomer of the plurality. The arrangement is secured and the plurality of liquid crystal elastomers cured.
