Numerical Study on the Effect of Graphene Sheet Alignment on Thermal Conductance of Graphene Form

Graphene foam is a three-dimensional structure made up of graphene. It provides conductive network with excellent heat transfer performance due to the outstanding features of the graphene. The dimensions of the graphene sheets in the foam structure and their alignment have significant impact on the thermal properties of graphene foams. In the present paper, the heat transfer performances of graphene sheets with different alignment have been studied and molecular dynamics simulations were carried out to investigate the influence of alignment angle of graphene sheets on the thermal conductive characteristics. The alignment forms various patterns, and the change of thermal conductivity depends on the alignment pattern.
