Role of geometric shapes on the load transfer in graphene-PMMA nanocomposites

In this paper, a series of pull-out simulations of graphene are carried out to investigate the influence of two-dimensional (2D) geometric shapes of graphene nanosheet on the interfacial load transfer in graphene/PMMA nanocomposites by means of molecular dynamics (MD) simulation. Three common types of shapes, i.e. rectangle, trapezoid and sawtooth, are considered. It is found that the drastically improved pull-out force and interfacial shear...
