| Outline of Final Research Achievements |
Photomobile polymer materials, which macroscopically deform upon irradiation with light, have attracted much attention because of their potential in various applications such as microrobotics. However, there still remain several issues to be challenged for practical use in their response rates and mechanical toughness.
In this study, we developed a novel class of photomobile materials with interpenetrating polymer network (IPN) structures. Amorphous poly(alkyl methacrylate)s were incorporated to LC azobenzene polymer (PAzo) films. The IPN films showed reversible bending upon irradiation with UV and visible light as well as pristine PAzo films. The optical and mechanical properties of photomobile polymer materials can successfully be controlled by forming IPN structures with adequate amorphous components. It was found that the interaction between different components plays significant roles in determining performance of IPN films as well as the properties of homopolymers.
