ABSTRACT

Multi-bilayered films with precisely controlled layer thickness were constructed for structural color and their reflection angular dependences were investigated. For wide angle structural color, it was intended to the macro irregularity of multi-bilayered films by randomly dispersed micron size multi-bilayered films in PDMS matrix. In addition, on-off switching of the reflection was examined with respect to the molecular orientation behavior of azobenzene chromophores by annealing and light irradiation.
