Flexible, Angle‐Independent, Structural Color Reflectors Inspired by Morpho Butterfly Wings

Flexible, Angle‐Independent, Structural Color Reflectors Inspired by Morpho Butterfly Wings

Thin‐film color reflectors inspired by Morpho butterflies are fabricated. Using a combination of directional deposition, silica microspheres with a wide size distribution, and a PDMS (polydimethylsiloxane) encasing, a large, flexible reflector is created that actually provides better angle‐independe...

Zusammenfassung:Thin‐film color reflectors inspired by Morpho butterflies are fabricated. Using a combination of directional deposition, silica microspheres with a wide size distribution, and a PDMS (polydimethylsiloxane) encasing, a large, flexible reflector is created that actually provides better angle‐independent color characteristics than Morpho butterflies and which can even be bent and folded freely without losing its Morpho‐mimetic photonic properties.
