Mechanical properties of artificial composites have been reported to reach their saturated values within conventional regime. However many kinds of biomaterials show unprecedentedly high performances of mechanical properties, for instances, fracture toughness of nacre of abalone shells, impact resistance of the stomatopod dactyl clubs, and stiffness-damping combination of teeth. In this study, we utilized layer-by-layer assembly method to fabricate 2D and 3D organized nanostructures with anisotropic nanomaterials to mimic structures of biocomposites as well as their exceptional mechanical properties. We modulated mechanical properties of the composites by controlling spatial organization of anisotropic nanostructures and the intermolecular interactions at organic and inorganic interfaces. We could conclude that the anisotropic organization of nanomaterials in 2D and 3D spaces with controlled interfaces has an important role to surpass limit of conventional nanocomposites. |
