Abstract
Characteristics of laminated graphene oxide (LGO) nanocomposite, expected for high functional composites, are known to be related to its microstructure. In this study, we investigated influences of both hydrogen-bonding and cross-linked network structures on initial stiffness and yield stress by molecular dynamics simulations. Our results showed each structure improved the mechanical properties, and the combination of these structures made the properties stronger. Moreover, we revealed the physical origin of the enhancement is caused by cross-linked networks generate stretched polymers that connect graphene sheets. Our study is expected to give a suggestion to appropriate selection of materials for highly performance LGO nanocomposite.
