| Abstract Scope |
A single piece of two-dimensional (2D) nanomaterials is too delicate to be useful in most applications for example, high-performance electrodes in energy storage. Assembling these nanomaterials into three-dimensional (3D) scaffolds to achieve superior overall performance with multiple functionalities has attracted growing interests, yet this is challenging in manufacturing. I will start with the introduction of a capillary crumpling technique to address this challenge. In this technique, 2D nanomaterials will experience large deformation and severe instability under evaporation-induced compression to create spacings when assembled, thereby minimizing restacking and retaining the large surface areas of 2D nanomaterials in the assembled 3D architectural structures. I will then present both quantitative theory and coarse-grained computational models to reveal crumpling and self-assembly mechanism in parallel with comparison with available experiments. After that, the properties of assembled 3D architectural structures will be demonstrated in terms of accessible area and mechanical strength. |
