| Outline of Final Research Achievements |
The properties of nanocarbon hybrids were investigated via molecular dynamics simulation. It was shown that polycyclic aromatic hydrocarbons (PAHs) are spontaneously encapsulated into a carbon nanotube, and form dimers which fill the CNT and result in a PAH stack. Indentation simulation for graphene-CNT hybrid films revealed the hybrid film of a single CNT-array exhibits softening at large deflections, while the hybrid film of two CNT-arrays exhibits hardening at large deflections. Tensile test for rebar graphene showed that graphene is strengthened via CNTs which are arranged at their grain boundaries. The thermal conductivity (TC) of a graphene/hBN heterobilayer with interlayer sp3 bonds is calculated, and it was shown that its TC is sharply reduced by the existence of interlayer sp3 bonds, and the TC has its minimum.
