Self‐Supporting Elastic Film without Covalent Linkages as a Hierarchically Integrated β‐Sheet Assembly

Hierarchic self‐assembly: The formation of a self‐supporting elastic film without the use of macromolecular materials is described. The film is prepared by using a peptide‐containing amphiphile that has three or four consecutive leucinate residues. The amphiphile initially forms β‐sheet structures, which stack in a fastenerlike fashion between the side chains of leucine within the different β‐sheets (see picture).
