In this paper, the anisotropic thermal conductivity characteristics of graphene wrinkles are observed for the first time using a non-equilibrium molecular dynamics method. Our results reveal that the wrinkling level has little effect on the thermal conductivity along the wrinkling direction. However, the wrinkling level plays an important role in the reduction of thermal conductivity along the texture direction, which results from the contributions of increased bond length, von Mises stress, broadening of phonon modes and G-band redshift. These results indicate that graphene wrinkles can be a promising candidate to modulate thermal conductivity properties in nanoscale thermal managements and thermoelectric devices.
