COMPARISON OF CARBON NANOFIBERS AND ACTIVATED CARBON ON CARBON DIOXIDE FOAMING OF POLYSTYRENE

摘要

Carbon nanofiber and activated carbon particles are two forms of carbon with different shape and surface properties. These two carbon materials are used as additiveucleation agents in polystyrene extrusion foaming. Activated carbon particles with different moisture contents are used to investigate the effect of moisture as the co-blowing agent on the finished foam products. Carbon dioxide is used as the blowing agent. Morphology and thermal properties of extruded foams are reported and compared with the characteristics of these two additives.
