We report compressive mechanical response of graphene foams (GFs) and the thermal resistance (R-TIM) between copper (Cu) and GFs, where GFs were prepared by the chemical vapor deposition method. We observe that Young's modulus (E-GF) and compressive strength (sigma(GF)) of GFs have a power law dependence on increasing density (rho(GF)) of GFs. The maximum efficiency of absorbed energy (eta(max)) for all GFs during the compression is larger than similar to 0.39. We also find that a GF with a higher rho(GF) shows a larger eta(max). In addition, we observe that the measured R-TIM of Cu/GFs at room temperature with a contact pressure of 0.25 MP applied increases from similar to 50 to similar to 90 mm(2) K/W when rho(GF) increases from 4.7 to 31.9 mg/cm(3).
