Bioinspired Gyroid Photonic Crystals
Unlike usual pigments, natural Science and Optoelectronic Science develop
photonic crystals like butterfly’s a unique technique—trapping of structural
wings are able to reflect shining coloration (TOSC)—through which human-
and beautiful colors due to the made butterfly-wing-like gyroid photonic
inner ordered bicontinuous crystal films are carried out by spontaneous
network microstructures called self-assembly of polymeric materials. By
gyroid. Gyroid-structured photonic manipulating TOSC, their human-made
crystals could theoretically exhibit gyroid photonic crystal films in the solid
advanced optical properties as a state could exhibit any reflectance hue and
result of their highly interconnected controllable reflectivity in visible wavelength
network. However, the visible range you desired without the need to
gyroid photonic crystal could not introduce any additives or to synthesize new
be artificially fabricated currently compounds. Also, their gyroid films are highly
due to the extremely complicated flexible and possess switchable structural
structural shape and its downsizing coloration triggered by various stimuli such
to hundreds of nanometer. Prof. as heat, alcohol, solvent, and irradiation,
Yeo-Wan Chiang and his research being superior to natural butterfly wings. As
team at the Department of Materials a result, the mass production of the human-
made visible gyroid photonic
crystal films is accomplished.
It is applicable in the fields
of optical communication,
energy, light-emission,
sensor, and display.
