The solidification of two-dimensional liquid copper confined to graphene layers has been studied using molecular dynamics simulations. The results clearly show that the liquid copper undergoes an obvious transition to a crystal film with the decrease of temperature, accompanied by dramatic change in potential energy and radial distribution function. Moreover, five different simulation models are used to investigate the effects of the number of graphene layers on the mechanical properties of the composites. It is found that the strength and plasticity of the composites have been improved significantly.
