摘要：

Three-dimensional carbon honeycombs were experimentally discovered recently. In this work, we study the thermal conductivity of zigzag carbon foams with different sidewall widths. We found the anisotropic thermal conductivity along different directions. We noted that the local buckling introduced by the interconnections severely impedes the phonon transport. The phonon density of states was analyzed to compare the phonon modes in the planar and the interconnection regions. The structure-thermal transport property relationship obtained in this study provides important insights for future applications of three-dimensional carbon honeycombs, such as energy storage, catalysis, microelectronics, and the like.
