文摘
- •
Polycarbonate–graphene foams were prepared via 1- and 2-step scCO2 foaming.
- •
Thermal conductivity of foams increased linearly with augmenting relative density.
- •
Foams prepared via 1-step displayed higher thermal conductivities than 2-step foams.
- •
The addition of higher GnP amounts led to foams with higher thermal conductivities.
- •
GnP’s effect in enhancing conductivity was less marked with increasing its content.
