A new class of phototropic liquid crystal mixture comprises a liquid crystal host and one or more photodichroic dyes, wherein exposure of the mixture to an activating light causes a light-induced increase in order parameter of the mixture. In some examples, in the absence of the activating light, the phototropic mixture has a lower order parameter than the liquid crystal host, while in the presence of activating light, the phototropic mixture has a higher order parameter than the liquid crystal host. In some examples, upon exposure to the activating light, the phototropic mixture undergoes a phase transition from a material with a lower order to a material with higher liquid crystalline order. In some examples, activating light causes the mixture to transition from an isotropic phase to a nematic phase, from an isotropic phase to a cholesteric phase or form a nematic phase to a smectic phase.

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.

A shape-programmable liquid crystal elastomer. The elastomer comprising cross-linked and polymerized nematic, isotropic monomers with carbon nanotubes that are organized into a plurality of voxels. Each voxel has a director orientation such that each voxel of the plurality has a first state according to the director orientation and a second state according to cross-linkages of the polymerized nematic monomers. The elastomer transitions between the first and second states with exposure to an electric field.
