Controlled Three-Dimensional Motion of Liquid Crystal Polymers by Light
(0) There is a growing interest in the development of artificial muscle-like actuators, which are ideal for the realization of biomimetic movements by changing their shapes and dimensions when a potential is applied. Polymer actuators play a leading role in this field, because they provide such advantages as flexibility, light weight, low cost and quiet operation compliance. Recently there has been a growing focus on the study of soft actuator materials based on crosslinked liquid crystal polymers (CLCPs) due to their unique combination of the anisotropic aspects of LC phases and the rubber elasticity of polymer networks. Many theoretical studies and experimental investigation have demonstrated that a slight drop in the temperature across the isotropic-to-LC transition is able to cause a strong uniaxial deformation of CLCPs at nearly constant volume due to a change in the LC order. By incorporating azobenzene derivates into CLCPs as a trigger, photodeformation has been achieved upon irradiation of UV light.
