HYGRORESPONSIVE MATERIALS

Actuators powered by water hydrogen bonds

Nature Materials volume 20, pages 287–288 (2021)Cite this article

Subjects

Nanoporous tripeptide crystals mechanically deform upon water evaporation due to the strengthening of the water hydrogen bonding inside the pores, which causes the distortion of the surrounding supramolecular network, creating stresses that extend through the crystal lattice and result in actuation.
