Abstract
Biomimic silk fibers with refined crystalline structure were produced via incorporating cellulose nanocrystals into silk fibroin matrix to mimic the β-sheet crystallites in natural silk. The fibers exhibit excellent thermal and mechanical properties, attributed to the strong hydrogen bonding interactions between cellulose nanocrystals and silk fibroin as well as cellulose nanocrystal-induced ordered structure.
