Abstract:
In this work, we performed a theoretical study of the Young's modulus of carbon molecular structures in the form of multilayer graphene with vertically oriented carbon nanotubes (VO-CNTs). The carbon nanotubes that make up the molecular structures were of two types (zigzag and armchair). The studies were carried out by the molecular-mechanical method with the energy potential of AIREBO. It was found that the Young's modulus is higher for molecular structures of composites in which CNTs of different types are located along the zigzag edge of the graphene sheet. It is shown that the Young's modulus of the molecular structure with VO-CNTs on graphene containing zigzag and armchair nanotubes is higher than the Young's modulus of the molecular structure with VO-CNTs on graphene containing only zigzag CNTs. These results can be used in the design of electromechanical devices that include a molecular structure with VO-CNTs on graphene as an element base.
