摘要
Supercritical CO2 with ethanol as blowing agent foamed poly（methylmethacrylate） （PMMA） fiber at 308.15K and in the pressure range from 12-15MPa. The foam structure was detected using scanning electron microscope. It was found that the concentration of ethanol in the fluid is a major parameter to affect the foam structure.
