Outline of Final Research Achievements

Using multi-processes including nanoscale randomness, I achieved the fabrication process for large-area (80 mm square) and flexible Morpho-color materials. In these developments, I enabled double-ways, i.e. both the flexible mold and flexible replica, which increased largely a flexibility of the fabrication process. The realized color materials maintained the original and specific Morpho-color properties even under the flexible-film conditions. Moreover, they have mechanical strength and endurance against repeated bending, which are available for applications.
