| Research Abstract |
We have investigated photo-response behavior of multi-bilayred films having precisely controlled layer thickness prepared by stacking an azo-functionalized polymer liquid crystal and polyvinylalcohol alternatively, PVA. The multi-bilayered fims reflected a light of specific wavelength depending on the layer thickness and refractive index, and showed the reversible change in the reflection intensity by irradiation with visible and UV lights. The rate of the change in the reflection intensity was increased by copolymerization of monomers having biphenyl side chain. In addition, the angle dependence of the reflection intensity was improved by providing the micro-wrinkle structure to the multi-bilayred films.
