Abstract
The microstructure of polystyrene foams fabricated using carbon dioxide as blowing agent under different processing conditions including decompression rate, foaming temperature and saturation pressure, was investigated using SEM. The effects of saturation pressure on the time and temperature dependence of the cell density of foamed polystyrene are discussed in terms of the time-temperature superposition principle. 16 refs.

Abstract
The fabrication of a novel carbon foam with high strength and high thermal conductivity via pyrolysis and graphitisation at high pressure and high temperature of a coal tar-based mesophase pitch precursor containing various proportions of graphite nanoparticles is described. The foams were characterised by SEM, compression testing, thermal conductivity and XRD, and the results are discussed. 14 refs.
