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.
