Chameleons can famously change their color, but when scientists have tried to imitate these abilities in various materials, they haven’t been completely successful. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a highly flexible film made of cellulose nanocrystals that changes color when stretched. ACS’ Headline Science shows how the chameleon-inspired material can morph hues with stretching, pressure and humidity.
