Abstract
Hydration-responsive shape-memory keratin composite fibers are provided. These fibers have a keratin network structure formed by keratin α-helices bonded by disulfide bonds. Incorporated within the structure are cellulose nanocrystals (CNCs), which provide hydrogen bonds and stabilize the α-helix structure, introducing a hydration-responsive switch. Specifically, the CNCs are configured to arrange and connect the keratin α-helices, aligning their coil axis along the fiber axis.
