New Material Can Change Its Color and Texture Like a Cuttlefish - IEEE Spectrum via @IEEESpectr…

Nanomaterials have offered scientists a variety of ways to pursue biomimicry. We’ve seen nanorods used in polymers to mimic the ability of amphibians to grow back lost limbs or to duplicate the adhesive properties used by geckos when they walk on ceilings . Now researchers at the University of Nebraska-Lincoln (UNL) have looked at the camouflage capabilities of the cuttlefish to develop a structure than can change both its color and texture within seconds of being exposed to pulses of light . "Changing color is relatively easy; a TV can do that,” said Li Tan, an associate professor a UNL, in a press release. “Changing texture is harder. We wanted to combine the two." In research published in the journal Applied Materials and Interfaces , the researchers were able to produce this effect by placing colloids inside a multilayered structure consisting of “a thermal insulating ...
