Anna J. Svagan, My A. S. Azizi Samir and Lars A. Berglund Biomimetic Foams of High Mechanical Performance Based on Nanostructured Cell Walls Reinforced by Native Cellulose Nanofibrils Advanced Materials 20
A bioinspired foam in which cellulose nanofibrils are used to reinforce cell walls (ca. 3 µm) is presented. The nanocomposite foams are prepared by a lyophilization technique and show composite structure at the cell-wall scale. The nanocellulosic network shows remarkable mechanical performance, expressed in much-improved modulus and yield strength compared with the neat starch foam.
