Polystyrene/multi-walled carbon nanotube (PS/MWCNT) nanocomposite foams were prepared in order to determine if these foams exhibited a reduced thermal conductivity in comparison to pristine polystyrene foam. The thermal conductivity of foams can be broken down into three modes of conduction: gas conductivity, solid conductivity, and radiative conductivity. The PS/MWCNT foams had decreased gas and radiative conductivities in comparison to the pristine PS foam; however, the solid conductivity ...
