摘要：
Poly (methyl methacrylate) (PMMA) sheets were radiated by Co-60 gamma-ray in air and then irradiated PMMA foams were successfully prepared by supercritical CO2 (SC CO2) as a physical blowing agent via pressure quench method. The effects of radiation dose on the cell morphology and structure of the obtained foams were studied. The results showed that the foams possessed spherically closed cell structure with uniform cell size. The gamma-ray irradiated PMMA sheets had a high cell density than those virgin PMMA.
