title = "Comparison of carbon nanofibers and nanoclay on rheology of polystyrene under supercritical carbon dioxide",
abstract = "Carbon nanofibers (CNFs) and nanoclay have been used as reinforcement additives and nucleation agents in the polystyrene (PS) foaming process with supercritical carbon dioxide (CO2) as the blowing agent in our laboratory. The extrusion foaming process, as well as the final foam structure, is largely controlled by the complex rheological behavior of the PS-CO 2-nanoparticle mixture. In this study, steady state shear viscosity of PS in the presence of the blowing agent CO2 and nanoparticles was measured by a modified Couette rheometer. It was found that, under the same temperature and CO2 pressure, CO2 reduces viscosity less for PS-nanoclay composite than either PS-CNFs composite or PS.",
