Moreover, CNTs content significantly affects the pore structure and mechanical properties of carbon foams. As CNTs content increase from 0 wt% to 1.5 wt%, the number of bubble pores in carbon foams significantly decreases and the distribution of template pores is more uniform. Apart from variation in pore structure, the fabricated CNT/carbon foam shows an enhanced mechanical strength. Mechanical properties and thermal conductivity of CNTs/carbon foams can be adjusted by varying content of CNTs. As the result, the compressive strength first increases from 57 MPa to 160 MPa and then decreases to 82 MPa, when CNTs content increases from 0 wt% to 1.5 wt%. This strengthening effect is primarily attributed to the uniform distribution of CNTs under mechanical loading, which promotes crack deflection, crack branching and bridging.
