제목 Programmable stimuli-responsive liquid crystalline polymers
초록 Liquid crystalline polymers have been proven capable of converting various stimuli input (light, heat, chemicals) into mechanical work. We investigated photomechanical and thermomechanical responses of monolithic self-assembled liquid crystalline polymers wherein global manipulation of liquid crystal alignments at a molecular level enabled programmable mechanical actuation on a macroscopic scale upon exposure to light irradiation or to thermal sources. Engineered mechanical responses in liquid crystalline polymer include in-plane bending, oscillation, and out-of-plane torsion. Furthermore, patterning nematic director voxel-by-voxel transformed flat two-dimensional polymer sheets into three-dimensional objects as complex local mechanical actuations were programmed within the monolith.
