| Research Abstract |
We developed photomobile materials using crosslinked liquid-crystalline polymers, which could convert light energy to mechanical work directly. It was found that photomobile property was affected by molecular alignment of mesogens and crosslinking density of the polymers. The crosslinked liquid-crystalline polymers laminated to polyethylene films with an adhesion layer showed various three-dimensional movements, such as rotational and translational motions, by photoirradiation. We prepared crosslinked liquid-crystalline polymer fibers with photomobile property. The directional control in photomobility of the polymer fibers may lead to potential applications in artificial muscles and light-driven actuators.
