Interfacial Stress Transfer in a Graphene Monolayer Nanocomposite

Interfacial Stress Transfer in a Graphene Monolayer Nanocomposite

It is demonstrated from stress‐induced Raman bands shiftsthat stress can be transferred from a polymer matrix to a graphene monolayer (see image) in a model nanocomposite. It is shown further that the behavior can be modeled using continuum mechanics and that the interface between the graphene and t...

Zusammenfassung:It is demonstrated from stress‐induced Raman bands shiftsthat stress can be transferred from a polymer matrix to a graphene monolayer (see image) in a model nanocomposite. It is shown further that the behavior can be modeled using continuum mechanics and that the interface between the graphene and the polymer breaks down at a shear stress of the order of 2 MPa.
