| Research Abstract |
In this study, we examined synthesis and application of a novel liquid crystalline polymers and their crosslinked polymers having movable crosslinks based on a polyrotaxane (PR) structure. PR has a supramolecular structure in which linear polymer penetrates a number of the cyclic molecules, referred to as molecular necklace. We synthesized a liquid crystalline PR having movable side chains by binding liquid crystal groups in the cyclic molecule of the PR. And succeeded in synthesizing a liquid crystalline gel can be swollen with the low molecular weight liquid crystal in the slide-ring polymer.We found the possibility of as a soft actuator by examining temperature response characteristics, swelling properties, and the mechanical properties of the liquid crystalline slide-ring gels.
