제목 Liquid crystal elastomer single filmactuator with reversible curvature inversion
초록 Multi-curvature transformation of a surface is an one of very required ability to present complicated shape as well as flexibility in locomotion for soft actuator. Here, we have demonstrated a one pot approach to fabricate a single film of liquid crystal elastomer(LCE) presenting reversible curvature transformation inversion with thermo-stimulus. Photo-crosslinking of reactive mixture including non-reactive mesogens provide a formation of A liquid crystal director is programmed on single film and a method capable of inducing a crosslinking density gradient through the thickness of LCE film. Because of the density gradient, the film pre-curvatured structure that is deformed towards less dense part after extraction of the non-reactive mesogens. The results highlight the formation of density gradient is easy but effective strategy to prepare single film that is capable of reversibly transforming in multi-shapes.
