Abstract

original image

Dry and bright: To mimic the wings of the displayed Morpho butterfly, a new decorative material that exhibits both structural color and superhydrophobicity (the “lotus effect”) was developed by taking advantage of the unique structural properties of an inverse opal film, which was fabricated by the self-assembly of polystyrene spheres and silica nanoparticles.
