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.

我们研究了由偶氮功能化聚合物液晶和聚乙烯醇（PVA）堆叠而成的具有精确控制层厚的多层膜的光响应行为。多层膜根据层厚和折射率反射特定波长的光，在可见光和紫外光的照射下，其反射强度呈现可逆变化。具有联苯侧链的单体共聚提高了反射强度的变化率。此外，通过为多层薄膜提供微皱结构，改善了反射强度的角度依赖性。
