(2D) nanomaterials, an emerging
research area, still remains largely unexplored. The strong interlayer
attraction between 2D nanosheets leads to face-to-face stacking rather
than edge-to-edge coupling. We demonstrate, for the first time, how
one can induce and control an edge-to-edge self-assembly process for
2D nanomaterials. The extremely weak van der Waals coupling and strong
anisotropy of ReS2 allow us to realize an oriented self-assembly
(OSA) process. The aspect ratio of the resulting ReS2 nanoscrolls
can be well controlled. In addition, we perform simulations to further
explain and confirm the OSA process, demonstrating its great potential
to be expanded as a general edge-to-edge self-assembly process suitable
for other 2D nanomaterials.
