Abstract: Many living organisms have amazing control over their color, shape, and morphology for camouflage, communication, and even reproduction in response to interplay between environmental stimuli. Such interesting phenomena inspire scientists to develop smart soft actuators/robotics via integrating color-changing functionality based on polymer films or elastomers. However, there has been no significant progress in synergistic color-changing and shape-morphing capabilities of life-like material systems such as hydrogels. Herein, we reported a new class of bioinspired synergistic fluorescence-color-switchable polymeric hydrogel actuators based on supramolecular dynamic metal-ligand coordination. Artificial hydrogel apricot flowers and chameleons have been fabricated for the first time, in which simultaneous color-changing and shape-morphing behaviors are controlled by the subtle interplay between acidity/alkalinity, metal ions, and temperature. This work has made color-changeable soft machines accessible and is expected to hold wide potential applications in biomimetic soft robotics, biological sensors, and camouflage.

Photonic crystals cause active colour change in chameleons
TL;DR: It is shown that chameleons shift colour through active tuning of a lattice of guanine nanocrystals within a superficial thick layer of dermal iridophores, which allows some species to combine efficient camouflage with spectacular display, while potentially providing passive thermal protection.
Recent advances and challenges in designing stimuli-responsive polymers
Fang Liu,Marek W. Urban +1 more
TL;DR: In this article, a review examines physico-chemical requirements necessary to achieve stimuli-responsiveness in heterogeneous polymer networks as well as discusses recent developments and future trends while individual structural components of polymeric networks are responsible for localized chainresponsiveness, desirable spatial and energetic network properties are necessary for collective and orchestrated responsiveness to external or internal stimuli.
