Nanomaterial copies butterfly colors

Researchers have figured out how to recreate the bright, beautiful colors of butterfly wings, as well as their ability to strongly repel water. The colors of a butterfly’s wings are the result of an unusual trait—the way they reflect light is fundamentally different from how color works most of the time. A team of researchers at the University of Pennsylvania has found a way to generate this kind of “structural color.” Shu Yang, associate professor in the department of materials science and engineering, led the research. She and colleagues report their findings in the journal Advanced Functional Materials. “A lot of research over the last 10 years has gone into trying to create structural colors like those found in nature, in things like butterfly wings and opals,” Yang says. “People have also been interested in creating superhydrophobic surfaces which is found in things like lotus leaves, and in butterfly wings, too, …
