Formation of binocular-like structure using graphene nanosheet and carbon nanotubes

Binocular-like carbon structure was successfully fabricated using forced-field-based molecular dynamics simulations. The mechanism for the self-scrolling of graphene sheet using carbon nanotubes as template was analysed. By analysing the self-scrolling process, it was found that the van der Waals interactions were responsible for the formation of the binocular-like carbon nanostructures. Furthermore, the position and number of carbon tubes influenced the self-scrolling process. Moreover, the mechanism was also discussed. Our theoretical results will provide researchers a powerful guide and helpful assistance in designing better targeted programmes in experiments.
