| Research Abstract |
In this study, we have tried the fabrication of multi-layered liquid crystal polymer films that has photomechanical activity by visible light.
In the results of investigation, the method of peeling of film from glass-substrate without stress, and the fixing of main chain of liquid crystal polymer in the multi-layered film after the spin-coating, were achieved. The azobenzene liquid crystal polymers with rapid reverse isomerization, visible light sensitive, orientation properties, were obtained in the cycle of molecular-designing. However, the photo-mechanical activity induced by only visible light was not achieved.
