A novel nanostructured composite film (see figure) that takes advantage of two different natural materials—layered nacre and the marine adhesive of mussels—is prepared. L ‐3,4‐Dihydroxyphenylalanine (DOPA) molecules impart unusual adhesive strength to the clay composite and the hardening mechanism found in the natural “cement” plays an equally important role in the strengthening of the “nanostructured nacre”.
