Resum
The thermal conductivity of polycarbonate–graphene nanocomposite foams was studied as a function of relative density, developed cellular structure and graphene concentration. Two types of supercritical CO2 foaming processes were employed to obtain foams with a wide range of relative densities and cellular morphologies. The thermal conductivity of unfoamed nanocomposites increased in more than two times upon addition of 5 wt% graphene. Foaming led to lowered thermal conductivity values, as low ...
