Special Issue Information

Dear Colleagues,

Systematic research efforts have been directed towards developing nanostructured materials, such as carbon nanotubes and their complex structures. The recent success in assembling carbon and non-carbon nanotubes together creates opportunities for the incorporation of these innovative multilayered structures in nanodevices, and in applications for nanoelectronics and biomedicine.

Experimental studies towards determination of the properties of carbon and non-carbon nanotubes are constrained by experimental difficulties regarding the characterization of nanomaterials at the atomic scale. For this reason, the theoretical studies—both analytical and numerical, directed towards predicting their mechanical properties—have received much attention.

This Special Issue will focus on the modeling and numerical simulation of the mechanical properties of carbon and non-carbon nanotubes and their complex structures, such as heterojunctions, nanotube-reinforced composites, and nanotube networks. Achievements in theoretical modeling of the assembly of carbon and non-carbon nanotubes into multilayered heterostructures and optimization of their design are also of great importance.

Surface landscapes have vague impact on the mechanical properties of graphene. In this paper, single-layered graphene sheets (SLGS) with regular wrinkles were first constructed by applying shear deformation using molecular dynamics (MD) simulations and then indented to extract their mechanical properties. The influence of the boundary condition of SLGS were considered. The wrinkle features and wrinkle formation processes of SLGS were found to be significantly related to the boundary conditions as well as the applied shear displacement and velocity. The wrinkling amplitude and degree of wrinkling increased with the increase in the applied shear displacements, and the trends of wrinkling wavelengths changed with the different boundary conditions. With the fixed boundary condition, the degree of graphene wrinkling was only affected when the velocity was greater than a certain value. The effect of wrinkles on the mechanical characterization of SLGS by atomic force microscopy (AFM) nanoindentation was finally investigated. The regular surface wrinkling of SLGS was found to weaken the Young’s modulus of graphene. The Young’s modulus of graphene deteriorates with the increase in the degree of regular wrinkling.
