Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid crystal film comprising: cross-linked and polymerized, nematic monomers comprising a ratio mixture of a diacrylate and an amine; and a topographical defect within the cross-linked and polymerized, nematic monomers, the topographical defect having a first state and a second state, wherein the liquid crystal film is an elastomer having a glass transition temperature that is less than about 20° C. and the topographical defect is configured to assume the first state with a presence of a stimulus and to assume the second state in an absence of the stimulus. 2. The liquid crystal film of claim 1 , wherein the nematic monomers are selected from the group consisting of acrylates, methacrylates, thiols, vinyl, epoxides, and amines. 3. The liquid crystal film of claim 1 , wherein the diacrylate is 1,4-bis-[4-(6-acryloxyloxyhexyloxy)benzoyloxy]-2-methylbenzene and the amine is n-butyl amine. 4. The liquid crystal film of claim 1 , wherein the polymer includes a mesogen.
